SMOKE MACHINE

A smoke machine (also called a fog machine) is a device that produces a thick artificial vapor used for visual effects.

What it does

A smoke machine creates a dense cloud that looks like smoke or fog, mainly for:

• Stage performances (concerts, theater)
• Nightclubs and events
• Film and photography
• Halloween effects and decorations

How it works

Most smoke machines:

• Heat a special liquid (called fog fluid or smoke fluid)
• The liquid is usually water mixed with glycol or glycerin
• The heated liquid turns into vapor
• A pump pushes it out through a nozzle
• When it hits cooler air, it becomes visible as “smoke” or fog (AVGear.com)

What it actually produces

• It is not real smoke from fire
• It is a safe water-based vapor
• It looks like smoke because light reflects off the tiny particles in the air

Common uses

• Making stage lights and lasers visible
• Creating mood or atmosphere (e.g., spooky or dramatic scenes)
• Simulating fire, steam, or mist effects in film

Simple summary

A smoke machine is basically a fog generator that turns special liquid into visible mist for special effects. (en.wikipedia.org)
