How Does A Smoke Machine Work?
How it works.
Today, most fluid-based fog machines work by rapidly heating a mixture of water and glycol, producing a vapor.
The expanding vapor is forced out of a nozzle where the warm, moist vapor mixes with the cooler air to form fog.
Is smoke machine smoke bad for you?
As long as your fog machine is used properly it is perfectly safe to breathe. Most fog machine fluids are made from a water and glycol solution that is not considered to be hazardous, however it may cause respiratory or throat irritation problems in some people.
Is there a difference between smoke and fog machines?
Smoke machines produce a similar effect to low fog machines, however the heated smoke produced by smoke machines rises and dissipates around the room, whereas low fog machines produce cold liquid particles and the fog remains close to the ground. Use smoke machines for: shows, concerts, parties, spooky effects.
Do smoke machines use dry ice?
Machines that use dry ice work by continually heating water, to keep the fog flowing. Simple machines are also available to make dry ice or to solidify air. Dry ice is cold enough to cause frostbite – use protective gloves when handling it.
What is stage smoke made of?
Theatrical smoke can be made from water vapor, which is safe. It can also be made with liquid nitrogen or carbon dioxide (from dry ice). In both these cases, the fog is made when water vapor in air condenses.
