Thread: Co2 cryo jet fog effect

does anyone know how to build this thing are where i can get on the is cheap. everone is talking me out of fire (with good reason) so i thought this would be a little safer.


check it out

My dad and I built a CO2-powered cannon blast for a parade float, when I was in high school. He picked nitrous oxide (common vernacular: NOS) solenoid valves. On the float, we also had the CO2 flow over a tube connected to water, so it would pick up the water and atomize it along with the C02 stream. This one, however, looks like it's pure C02, because the spray doesn't stick around at all.

All ready "Goes Up In Smoke!"
Or so it sure seems!??
Could be a neat looking deal. My tour is much more of a "parlor" experience, small groups looking at and listening to me telling them things in a small dark room.

Would be great for an alien haunt. Or when u open your front door to the tot's

PLEASE BE CAREFUL PEOPLE!!! We're talking CO2 here. The same stuff that is used to smother various types of fires. Why? Because it depletes the OXYGEN. Yea, that same stuff we humans breathe to keep living. Can you say "Asphyxiation"?

Know the hazards of what you are using in your haunt enviroment.

Definately would not want 3 of these bad boy's going off in your garage haunt, or one for that matter. It would be like the Cyberdyne lab, "Put these on"

I think this prop is outside. CO2 is inert. Not likely to be a concern in this situation. Inside a closed garage. Yeah that would be a bad idea. But as you can see by the video CO2 is used often in even indoor stage events. One might think those blasts of CO2 have volume, but what you are seeing is a highly compressed gas expanding rapidly. The actual volume as compared to the ambient air is minor. Certainly nowhere near the 5% danger level. Or even the 1% irritation level. The gas is 1.5 the density of air, so it will drift to the floor and disperse rapidly. Notice that a permit is not required to use this prop. That in itself establishes some aspect of inherent safety.

Ok guys this is going to be outside for a haunted hayride. I cant find one for under
750. I just need to know how to build this thing. On my other post (help using fire) People
Have talked me out of the fire now Im trying co2 its safer than fire. So will someone please help me with this please

Just checked out a few of the cryo sites and are those expensive! Don't know how much total volume you need but how about a fire extingisher?

need something a little more than extingisher. there is about 18 are 19 ride that come through a night and there is 4 night
