Carbon dioxide-powered special effects device that creates dramatic fog blasts, cryo jets, or launches lightweight props – used in concerts, events, film, and live entertainment for instant atmospheric effects.
What is a CO2 Cannon?
A CO2 Cannon (CO2-Kanone, Cryo-Jet) is a special effects device that uses compressed carbon dioxide to fire spectacular bursts of fog, cryo jets, or even light props. The effect is immediate, dramatic, and relatively safe.
