Can
your smoke machines make coloured smoke / can I use coloured smoke
fluid?
No - it is not possible. Use lighting with coloured filters to colour
the smoke or use our our
electrically ignited theatrical pyrotechnic
coloured smoke cartridges. There is no way to create coloured smoke from a coloured fog fluid in a smoke machine. In depth answer...
Do
you sell smoke machines that do not require mains power?
Yes we do - our battery
powered smoke machines and our exterior
gas powered smoke gun. You could also use our pyrotechnic smoke
pellets and electronically detonated coloured smoke cartridges. The basic 1.1kW version of the Rocket
hand portable unit can run from any 1.5kva power generator without
any issues!
Do
smoke machines / hazers trigger fire alarms?
Two simple factors dictate this:
- density level
- sensitivity level / type of detectors
If the smoke or haze level is dense enough, both smoke machines AND HAZERS can trigger ionisation / optical, vesda (air sampling) or video smoke detectors/detection systems, depending on their sensitivity level. However, heat or "rate of temperature increase" detectors will NOT be activated. A high-end hazer (eg Phantom Hazer) when used at a low density level is slightly less likely to set off smoke detection systems than a smoke machine.
If you are uncertain of what type of smoke detector your venue has, consult with the head of maintenance or, as a last resort, notify the fire department and do a test run. You can also manually block smoke detectors by fitting a latex rubber glove over the detector, effectively preventing smoke laden air reaching the particle sensors.
If you need to test smoke detectors, blasting the smoke from one of our machines towards the detector will set it off. We also supply specialist units which heat the smoke so it rises up like that from a real fire.
Can
I use any brand of smoke fluid in my smoke machine?
Our job would certainly be easier if the answer was 'yes', but alas
the answer is NO and here's why:
Smoke generators are designed around a specific mixture of chemicals, with specific boiling ranges. Using a smoke fluid that, for example, is based on propylene glycol and water, which has a relatively low boiling range, through a generator set for glycerine / water (with a much higher boiling range) potentially can crack the chemical, forming unpleasant and potentially toxic compounds (acroleins, aldehydes etc). Even changing the amount of water in a mixture can have an effect.
All the major UK manufacturers agree about the potential dangers of mixing and matching smoke chemicals, and stress that so called 'generic smoke fluids' simply could not be relied upon to produce a consistent and safe smoke in every generator. The use of generic fluids or the wrong fluid in the machine regrettably keeps our service and spare parts department busy.
Safe smoke that is non-toxic to breathe in is your responsibility!
The use of generic smoke chemical in place of the manufacturer's recommended fluid leaves you wide open to all sorts of legal recourse relating to health & safety, reliability of your machine and servicing costs. It simply isn't worth the risk.
Do
smoke machines make you cough?
No they should not - and if you have experienced coughing it may
be due to the operator using the incorrect fluid or a cheap 'generic' smoke fluid to save
money - something we strongly advise against (see question above).
If you have a respiratory condition or are asthmatic, we don't recommend
you enter into an environment containing dense smoke. Occasionally people will experience a psychosomatic
reaction to seeing smoke and cough for the sake of it (even though
the smoke isn't actually causing this reaction in a physical sense).
Contrary to popular belief, our modern oil-based thermally generated
smoke/haze systems such as the Phantom
is least likely to affect those with a medical condition related
to their respiratory system as it does not produce a hygroscopic
particle (ie does not absorb moisture to make throats and eyes dry out). Contact
us for more information.
How important are the quoted smoke output volume rates?
The smoke output rate, usually quoted in cubic feet or cubic metres
per minute, are figures quoted by manufacturers of smoke machines
to try and illustrate how much smoke their units can produce. However,
the main issue is that no density level of the smoke in the volume is ever stated
which makes these output rates rather useless and very often over-exaggerated. Unlike water or air, smoke can vary in density from very thin to extremely dense. So without mentioning how dense the smoke is inside that given output volume, what does it mean? Even a small smoke
machine can produce 20,000 cfm, but the smoke spread out in a 20,000 cubic foot volume
would be very thin. The volume figure does not state the density, ie how thick or thin, the smoke actually is within that volume of space,
so technically would be correct! Whether you'd be too happy with a barely hazy density level if you were carrying out fire training or trying to visualise airflow is another matter. Without at least specifying a visibility level, any
smoke output figure is speculative and not necessarily accurate
nor constant with other manufacturers' figures. It is best to compare heat exchanger wattages for a more realistic comparison.
Can
smoke be ducted down lengths of hose from your smoke machines?
In most cases yes, this is possible. In depth answer...
Can
I use a smoke machine in the UK or Ireland since the public smoking
ban?
The provisions of the Health Act inasmuch as smoking is concerned
makes the possession of lit tobacco in a smoke-free place an offence.
Therefore, the issue of smoke machines does not feature unless the
smoke comes from lit tobacco - which - from any of our products
- is not the case!
Are
smoke machines toxic?
Not when you use the officially recommended fluid - we wouldn't
be selling them if they were!
In depth answer...
Can
I add scent / fragrance additives to smoke fluid so that it has
an aroma?
We don't sell aroma additives for fog fluid because a technical
report carried out by Brunel University on behalf of the Fire Brigade
Union in the UK recommended that any additives added to smoke chemical
to either add scent or colour the chemical should be removed, as
a large number of these additives were found to be related to known
carcinogens.
We are often asked about adding an electrical fault or burning smell to fluid, but another issue arises here - how do you know whether there is a real electrical fault or fire in your facility or whether it is the simulated aroma?
Do
you sell second hand units?
Occassionally we do. These are usually ex-hire machines or units
that have been discontinued or used for demonstrations. Please visit
our clearance page
to see the current list of items we have available. This list is
updated in real-time, so if it's not on the list, we don't have
it!
Can I put disinfectant in your smoke machines?
We are happy to provide smoke and aerosol generating equipment for customers to use with our water based smoke fluids whose active ingredients are recognised to have a bactericidal effect by their nature.
Customers can use their own disinfecting chemicals in the units, but in this case we can offer no warranty as to the safety, efficiency, flammability etc of the resulting fog and cannot warranty the equipment or its resulting effect as a consequence. The machine that could be most suitable for this type of application would be the Rocket with refillable canister(s) if using your own chemical or battery powered Mini Rocket for maximum portability.

So that customers can make consciencious decisions when purchasing equipment, here are the locations where the smoke machines and fluids are made:

What's the difference between a smoke machine and a fog machine?
The terms 'smoke machine' and 'fog machine'
both refer to the same type of unit.
'Fog machine' is the term used more in the United States, and 'smoke
machine' is the term mainly used in the United Kingdom and Europe.
Technically, the correct terminology is 'fog machine', as
the dictionary definition of fog is 'liquid particles suspended
in the air' (smoke/fog machines always vapourise liquid), whereas
smoke is 'solid particles suspended in the air'. Tradition along
with product descriptions over the decades has created this moniker
foible.

What is a smoke machine?
A smoke machine is an eletro-mechanical unit which produces clouds of smoke on demand. Smoke machines are used in theatres, nightclubs, film and television studios, theme parks and other entertainment applications to produce a smoke or fog effect which creates the illusion of fog, steam, smoke from a fire, and many other effects. They are also used to create 'safe smoke' in fire training scenarios, for leak testing of buildings and containers, testing efficiency of extraction systems and air flow in wind tunnels. Their size can range from that of a small water bottle to units that require mounting on a truck.

How does a smoke machine work?
A smoke machine, in its simplest terms, is a heating element which gets very hot, through which special fluid is pumped and is vapourised, thereby creating smoke vapour which exits the machine through the nozzle. Electronic circuitry ensures that the heating block in the smoke machine is kept between certain temperatures - too hot and the machine can 'crack' the chemical put through it creating toxic elements (or worse, turns into a flame thrower) - too cold and it generates a wet fog that leaves residue, or shoots out hot liquid.
/\ Back to top
What makes the smoke?
The most common type of smoke machine are those which use a water-based fluid, which is made up mainly of pharmaceutical grade glycol and water. There may also be other harmless chemicals in the fluid. Other types of smoke machine include dry ice machines which create a low lying heavy fog that uses dry ice (solid carbon dioxide), liquid nitrogen (which also creates a low lying fog), oil based smoke machines (similar in principle to water based machines, but uses an oil rather than a water base - the smoke can withstand much higher temperatures and is much more dense) and hazers (water based haze generators, mainly used to accentuate lighting than for conventional 'smoke' effects).

How much do smoke machines cost?
Smoke machines range widely in price, but as the Romans used to say, "Talia expensa sic empta" - you get what you pay for! We supply machines by the most reputable and consistent companies who, from our own experience, have a proven track record for reliability and excellent service should the need arise.
It is not in our interest to supply smoke machines that are unreliable - so we simply don't!
Smoke machines that are capable of operating continuously at high output do cost more but always have the power available for larger and more varied applications and will never require a re-heat 'dead band'.

Why should I get a professional machine instead of a cheaper version?
Professional machines are built to last for years of heavy operation either in fixed installations or in mobile applications. Most have no 'dead band', which means that they're always ready to make smoke on cue. They'll also be able to create lots more smoke a lot more quickly than cheap machines. Cheaper machines tend to automatically disable the pump while they're heating back up to temperature (the infamous 'dead band'!), and if you're using the machine in a time sensitive operation (in the theatre for example, where you have set cues for smoke to appear), this re-heating dead band could be happening just when you need to operate the machine on cue. The dead band may last for up to 1 minute - sometimes longer. Many professional machines have the ability to create continuous thick, dry, white fog output, and can create huge amounts of fog on demand.
We sell so many of our smoke machines to customers who have previously bought cheap 'party' machines for £40.00 from other retailers which have failed after only a few weeks. In the long run, it's false economy to use these 'toy' machines for use in professional applications. You'll notice a huge difference when you buy a machine that is "fit for purpose".
/\ Back to top
Are smoke machines dangerous?
Not if used sensibly with common sense. The only danger involved is
if the cases are opened (thus the risk of an electric shock - as
with every electical applicance) or if the casing of certain units
are touched (they can get very hot and may burn you). The smoke
which comes out of the smoke nozzle can also be very hot and often
there are notices on the machine itself warning of this. Under no
circumstances should you touch the nozzle that the smoke comes out
of - this will always be very hot (200 celcius +) when the unit is switched on (and
for quite a long time after it is switched off until it cools down completely).
Manufacturers often warn that you shouldn't install the machine
where the public can touch it or touch the hot smoke being generated.
The recommended distance ranges from 50cm - 3 metres. If you need
the smoke to appear in a public area, one way to get round this
safety recommendation is to use ducting to allow you to keep the
machine well away. Smoke machines should always be used in a well
ventilated area. In case the unit's temperature control malfunctions,
it is also wise not to install a machine above people's heads.
You must be very careful when using dry ice smoke machines in confined
spaces, as the carbon dioxide produced displaces oxygen in the air
and can cause suffocation. Actors shouldn't really lie down in the
smoke. There are alternatives to dry ice for low lying smoke, such
as chiller units for normal smoke machines and special all-in-one
low smoke generators. Think of the poor musicians in the orchestra
pit! The moisture in the cloud of dry ice fog sometimes de-tunes
their instruments. Check with the machine's manual for details.
You must use the fluid recommended by the manufacturer of the machine.
Using other fluid could not only damage the machine (and void the
warranty) but also create toxins in the smoke or make the machine
produce a wet fog which will leave residue on surfaces. Even a slight
change in the mixture of smoke fluid can cause this. Safe, non-toxic
smoke is your responsibility!
/\ Back to top
Are smoke machines a risk to health?
The smoke that is produced from either the water or oil based smoke machines that we sell is non-toxic and safe when you use the correct fluid. For more information, please read the health & safety documents for each type of smoke fluid we supply, which can be found on each smoke fluid product information page. For certain people with asthma or breathing problems, dense water-based smoke can cause eye, nose and throat irritation. It's not advisable to make or use a home-made smoke fluid mixture. Always use professionally manufactured fluid. Non-toxic smoke is your responsibility. You can search for: ESTA - fog and smoke working group - examining the effects of fog and smoke on health.
/\ Back to top
What safety advice is there for smoke machine use?
For water/oil based machines:
The nozzle and sometimes parts of the casing of the smoke machine
(except handle) get very hot. Don't touch the hot areas. The areas
that get hot may have a warning note on them. The smoke that
comes out of the nozzle is fairly hot and it is always advisable
not to go any closer than 50cm in front of it. It shouldn't be installed
where the public can get closer than 50 cm from the smoke from the
nozzle. Smoke machines shouldn't be installed directly over the
public's head. Sometimes they can spit hot fluid out of their nozzle
which can burn. Smoke machines are very high power electrical units,
often using more than 1kW of electricity, so
be careful not to use them in wet places such as outside or where they may get wet.
For dry ice machines:
Dry ice is sub zero and can cause frostbite if handled with bare
hands. Always use special gloves to handle dry ice. Dry ice shouldn't
be kept in airtight containers.
Don't let people lie down in dry ice fog. They could suffocate.
The CO2 produced by the dry ice is an asphxiant as it displaces oxygen. Dry ice machines boil water. This water is not only very hot but very
heavy too, so it's advisable not to struggle lifting these heavy
machines alone.
ALSO: Please be careful when refilling smoke machines with fluid - mop up any spills, as people can slip on any fluid left on the floor (it is more slippery than water).

How long does the smoke hang in the air for?
We supply different smoke fluids that will disperse at different rates. Some, such as Le Maitre's Quick Dispersing fluid and Antari's Super fast dissipating fluid can disperse as quickly as steam - disappearing seconds shortly after exiting the smoke machine nozzle, making it great for effects where a large build up of fog is not wanted. Other fluids make smoke that hangs in the air for hours. Our Phantom Hazer's output will hang for 3 - 4 hours + and can remain persistent even in very hot environments. It all depends on the application and the smoke machine you are using, but if the smoke machine is in a theatre or other location where ventilation is an issue, a fairly quick dispersing fluid should be used so that the location doesn't get fogged up too quickly. A nightclub would normally use a long lasting fluid so the smoke picks out light beams and so that they don't have to keep activating the smoke machine which tends to bring attention to itself (or ideally use a hazer).

How long do smoke machines take to heat up for operation?
Some conventional machines take a minute or two, some five or ten, and some longer. Generally the heat-up time is mentioned on our product information page. Many cheaper 'domestic' party smoke machines will have a 'dead-band' which is when the smoke machine needs to re-heat and stops itself from being operated while this happens. This can be a problem when in a situation where smoke needs to appear on cue such as on television or film or at a theatre, but is ususally fine for parties or home use when this isn't so much of an issue.

Do you sell machines that can be used without electrical power?
Yes - our battery powered smoke machines, and the exterior gas powered smoke gun for outdoor use. We also have a 12v vehicle security smoke screen for your vehicle's security and a 24v unit. You could also use our smoke pellets which are compact and affordable (UK only).

Can I duct smoke down a length of hose?
On most smoke machines, ducting adaptors are available to allow the connection of a length of flexible ducting hose to the front of the machine for remote smoke placement. It is cruically important that there is a gap between the output nozzle of the smoke machine and the opening of the ducting hose. Smoke needs a good supply of airflow to form vapour (fog) properly when exiting the nozzle of the machine, whilst at the same time drawing in air to the opening of the duct. So attaching hose directly to the output nozzle of the machine with no air gap is incorrect and will lead to a very wet smoke, condensate in the hose, and other issues.
If smoke starts coming out of the machine end of the hose you are trying to put it down, this will be due to a restriction on the hose further down its length, or trying to duct smoke into an area or room with a higher air pressure than the room where the smoke machine is located.
We only recommend ducting smoke down to 25mm on our own machines, and even then only for 4 metres of hose length. Generally, the rule of thumb is 'the bigger the better' with regards to selecting a ducting hose diameter, and this can allow hose to be up to 10 metres in length without causing 'frictional losses' and creating 'back pressure', which is when the smoke is trying to exit from the same end of the hose you are trying to push it down. Larger diameter hose allows smoke particles to travel down it more freely without colliding with each other and the walls of the hose.
Deposition of condensated smoke fluid is inevitable in any ducting system. The choice of a Pea Soup brand smoke machine with their tiny smoke particle size minimises this deposition. (Rocket and Dragon and our PS31 and PS33 smoke generators).
Fans can be used to push smoke out so that the hose is effectively purged of smoke after each issue. This minimises deposition and gives the smoke positive pressure, ideal when carrying out leak tests. Our centrifugal blower fan can take in smoke directly. But you can also fashion your own ducting Y splitter so that clean air from a simple inline or computer cooling fan is pushed down one stem, where it combines with smoke from the smoke machine coming down the other stem of the Y. The resultant mixed fog and air exits the hose under slight pressure.

How do I clean my smoke machine?
After a while, smoke machines can get clogged up with carbon - a natural by-product of heating smoke fluid. Smoke fluid can be quite a viscous liquid, so it's almost unavoidable that the machine gets clogged over time. To avoid it happening, follow the instructions you get with your smoke machine with regards to cleaning it. Some suggest a litre of distilled water for every 5 litres of fluid that the machine uses, others suggest water and white vinegar after 40 hours of continuous operation. It is arguable that passing what is effectively an acid through the pump, fluid pipes, seals and heater block will not do it much good, and ultimately any vinegar that will be remaining in any of these components when you start using smoke fluid in the machine again will be vaporised so best re-start the machine outdoors.
If storing a smoke machine for a long time, passing deionised water through it before storing can help. This isn't necessary if the unit is being used every day, eg in a visitor attraction. They may also instruct you to take parts of the nozzle to bits and brush them clean, as they can also become coated in carbon. This is when a maintainable heating block is useful, as found in our machines (Rocket and Dragon). Our PS31 and PS33 smoke generators that self-purge themselves after each smoke issue, meaning the heating block never gets clogged, and we also have an optional air-line purge feature in our Dragon unit that can be made to special order.

What is 'dry ice'?
Dry ice is solid carbon dioxide gas. It's called dry ice because when it 'melts' it changes in state from a solid directly to a gas without ever becoming a liquid. This process is called sublimation. When dry ice is put into boiling water it sublimates and creates these clouds of thick heavy fog - cold water vapour and CO2, which clings to the ground (because it is cold and more dense than air). The fog is odourless and colourless as it is literally clouds of water droplets (and it can therefore leave the stage slightly wet). The Peasouper is a dry ice machine that self-contains this effect for convenient use.

What's the difference between dry ice, liquid nitrogen, oil and water based smoke machines?
Dry ice and liquid nitrogen smoke machines both create
a heavy low lying fog effect with water. The materials they use to create this
can be tricky to get hold of for most people,
hard to store, and the effect can now be easily created on demand
by new electronic water based versions. However, dry ice really does give the greatest low lying fog effect quietly, so if you can find a local dry ice supplier (or make it yourself with special attachments for large liquid CO2 cylinders) your life is easier.
Large US theme parks have been known to use LN2 foggers as it gives a superb and reliable
effect and leaves no residue or chemical mess. It also disperses
quickly and causes no irritation to even sensitive asthmatics (the
majority of the air we breathe is nitrogen). They also use pressurised water-misting
foggers in many water rides which just use normal water under high pressure (low running
costs for heavy use).
Oil based smoke machines produce smoke than can withstand much higher
temperatures than water based fog. Ideal for fire safety training
which may also include real flames (water based smoke would simply
evaporate and disappear into the flames if used in conjunction with
them). Oil based machines that we supply are less toxic - the hang
time of the smoke is so long that you have much less smoke chemical
in the air than with water based systems. Feedback from customers
suggest they are less irritating to breathe in for persons suffering
with existing breathing conditions. They are also ideal for fire
training scenarios, as the smoke doesn't layer or disappear at high
temperatures like that of a water based smoke.
Water based machines are now the 'standard' smoke machine in entertainment
applications. There are many different types of water based fluid
which hang in the air for a long time or disperse quickly like steam.
It's the easiest way to make controllable smoke at a reasonable
price which is one of the reasons why it's the most popular.

How do smoke and fog chillers work?
Fog chillers cool the conventional 'hot' smoke from
a conventional smoke machine to sub-zero temperatures so that it
sinks to the ground with a similar effect to that of dry ice or
liquid nitrogen. They can save money in the long-term for installations, as dry ice
and liquid nitrogen can be expensive to deliver and doesn't last very
long, even if correctly stored. Special molecular or quick dispersing
fluid is used with fog chillers for two reasons - it makes
the fog last the same length of time that dry ice fog would before
disappearing, and if longer lasting fluid was used when the smoke
warms up again it will rise and fill the room with normal fog that
hangs in the air.
Le Maitre make a popular fog chiller unit. They convert fog from the normal
smoke machine into heavy fog by chilling the fog to sub-zero temperatures
using a liquid CO2 cylinder. It's so much more easy and convienient
than dry ice and more easily stored for longer lengths of time.
Other chiller units are simply large refrigeration systems. They don't use any CO2.
Be aware that some 'fog chillers' require you to put dry ice or
conventional water ice into them to chill the fog (which doesn't
make them as convienient as chillers that don't use ice, but the
dry ice will last longer and doesn't produce water after melting so nothing needs to be drained away).

What is a hazer?
A proper hazer is a machine that creates a very fine even haze which is used to enhance lighting beams. Hazers don't create clouds of thick smoke like smoke machines for special effects. They're favoured by television studios as the haze is almost invisible (for the cameras to see through it) yet it picks out light beams like smoke does. There is a glut of cheap hazers which are actually no more than a small smoke machine with a fan which inevitably produce a very cloudy, 'clumpy' effect. We don't sell those because we don't think they provide a very good haze effect. See our hazers available.
/\ Back to top
What is the difference between a smoke machine and a hazer?
Smoke machines create thick white smoke, whereas hazers create a thinner haze effect which is barely visible but can definitely be seen when beams of light strike it. Hazers are often used when the blast of smoke from a smoke machine would be too intrusive or noisy. The visibility of smoke created by smoke machines means they're used for special effects, fire training, and all of the other applications mentioned on this site. Hazers can be left to operate continuously and inconspicuously. Most cheap hazers are just glycol smoke machines with a fan. Proper glycerine hazers (MVS, Neutron), oil crackers (DF50) and thermal oil hazers (Phantom Hazer) are what are described as 'professional hazers'.

How much does smoke machine fluid cost?
Check out our list of all smoke fluid we sell for prices. It can differ considerably for the more specialist mixes such as those which create a fog that disperses quickly or that is specially designed for use in the fog chiller units mentioned in an earlier question. Different fluid types made by different manufacturers cost different amounts, which is why 'generic' smoke fluids are seen as a cheap alternative. On the container it will say "suitable for use in most smoke machines". This is potentially dangerous. Only the recommended fluid should be used in your machine - see next question.
/\ Back to top
Do I have to use the fluid that the manufacturer makes for my machine?
This is a very good question. When you buy a smoke machine, the instruction manual you receive with it will tell you that you must use fluid that has been made by the same manufacturer for that machine. Using other types of fluid will invalidate the warranty and could damage the machine. Other fluids may work in the machine, but by no means all. They may create a sub-standard smoke that is unpleasant to breathe and contain toxins that can damage your health, or leave a residue on surfaces. They could also damage your machine. If you do use another manufacturer's fluid in your machine and need to get it repaired under warranty, the first thing the service engineer will do is use a special indicator to see if you've used the correct fluid or not. You will either then be charged for the repair, or it will be sent back to you unrepaired. If you want to see your smoke machine last a long time, we recommend you use the manufacturer's fluid. It is optimised for use in your machine and specifically tested and proven to be safe.
The main reason smoke generator manufacturers state that the chemical used should be their own is that generators are designed around a specific mixture of chemicals, with specific boiling ranges. Using a smoke fluid that for example is based on propylene glycol/water, which has a relatively low boiling range, through a generator set for glycerine / water (with a much higher boiling range) potentially can crack the chemical, forming unpleasant and potentially toxic compounds (acroleins, aldehydes etc). Even changing the percentage of water in a fluid mixture can have an effect.
A number of years ago all the major UK smoke machine manufacturers prepared and signed a joint letter stressing the dangers, or more accurately potential dangers of mixing and matching smoke chemicals, stressing that so called generic smoke chemicals simply could not be relied upon to produce a consistent and safe smoke in every generator.
The use of generic smoke chemical in place of the manfacturer's recommended fluid leaves you wide open to all sorts of legal recourse relating to health & safety, reliability of your machine and servicing costs.
Safe smoke that is non-toxic to breathe in is your
responsibility.

Why is some smoke machine fluid expensive?
Manufacturers use very pure pharmaceutical grade ingredients which have an impurity factor of one per billion or similar (very pure) plus the cost of transportation of bulky heavy fluid containers, often from overseas. Hazer fluid generally costs more than 'normal' smoke machine fluid, as it tends to be more concentrated, containing more active ingredient and less water than more traditional glycol based fog fluid.

Where does 'dry ice' get its name?
Because the ice is cold (sub-zero) but never gets wet when it melts because it sublimates (see earlier question) turning directly from a solid to a gas without ever becoming a liquid, unlike water ice.

Can I buy smoke fluid that makes coloured smoke?
No. Fluid that creates coloured fog has been tried, has never satisfactorily worked without seriously damaging the smoke machine and is not available anywhere. The best way to make coloured smoke is to use normal smoke fluid (white smoke) and to colour wash the smoke with coloured lighting. The white fog particles defract the light and make it look like coloured smoke.
You may see certain smoke fluids are coloured themselves (usually green, red, blue, pink) but the smoke released is white. This is simply a colour indicator to let you know what type of fluid it is in the bottle so you don't confuse them (say, quick dispersing or long lasting).
The alternative is to use theatrical coloured smoke pyrotechnics that actually make proper, real coloured smoke - but they have the potential to stain fabrics and materials the smoke comes into contact with and you should avoid breathing the smoke in.

What are "intelligent lights"?
Intelligent lights are light fixtures whose beams move and change colour and pattern. They can either use a mirror which moves the projected beam of light (scans or scanners), or move the whole lantern body (moving head). They often use DMX control via a computerised control system. Often used at concerts, discotheques, outdoor events, on TV and in the theatre.
