godd2 Posted February 18, 2011 Share Posted February 18, 2011 I have seen lately in many shows, black eyed peas at the super bowl and new brittany spears video, these vertical "smoke" cannons that shot up. What are they?Who makes these things and how do they work. I am assuming some type of CO2 under pressure but not sure. Can anyone explain these things. thank you Link to comment Share on other sites More sharing options...

Jivemaster Posted February 18, 2011 Share Posted February 18, 2011 CO2 jets are a pretty standard trade show item see Plasa show. They use a HUGE amount of CO2 and cost a lot, they have to be fed with liquid CO2 which makes supplies a little more difficult. Link to comment Share on other sites More sharing options...
Kevne Posted February 18, 2011 Share Posted February 18, 2011 You can actually get Smoke Machines that do a vertical jet of smoke. Infinately cheaper and much less hassle than using CO2 but in my opinion, not as impressive. You can actually pick them up really cheap now. In fact you can buy 2 for less than most people can hire you the CO2 equivalent. My link Link to comment Share on other sites More sharing options...
back stage man Posted March 3, 2011 Share Posted March 3, 2011 we are trying to do somthing like that ,we found that a fire extinguisher does the same effect but smaller(and cheaper)mike ;) Link to comment Share on other sites More sharing options...
kerry davies Posted March 3, 2011 Share Posted March 3, 2011 Time for the swift and boring reminder that all CO2 fire extinguishers carry the warning "Do not use in a confined space". Same goes for jets but as they use large amounts need just a little thought before use. Playing around with CO2 has freezing as well as asphyxiation hazards so isn't that advisable as a "game" and the effects jets use specialist hoses and equipment. Of course, in the case of our American cousins ........(fill in blanks). Link to comment Share on other sites More sharing options...
Brian Posted March 3, 2011 Share Posted March 3, 2011 ...and cheaper...How much do you guys pay for a refill? Link to comment Share on other sites More sharing options...
Ynot Posted March 3, 2011 Share Posted March 3, 2011 ...and cheaper...How much do you guys pay for a refill?Maybe 'they' don't.....Maybe it's just left for 'the management' to sort after they're found to be empty after the show's done... /cynic. That said, when we needed a specific effect with jets of 'steam' escaping as "Squidicus Giganticus" crushed Cpt Nemo's submarine in panto a couple of years back we did fall back on using up to half a dozen CO2 extinguishers from the wings. BUT we achieved this by talikng nicely to our extinguisher service guy who brought us a job lot of out of date units that were due for disposal. I would NOT recommend using any extinguishers from the working stock in your venue! Link to comment Share on other sites More sharing options...
back stage man Posted April 26, 2011 Share Posted April 26, 2011 we ended up getting a local fire extingisher componey to donate 6 free fire extingisher but there fire extigishers are $300.00 a peace and $50-$100.00 for refills mike. Link to comment Share on other sites More sharing options...
d_korman Posted April 27, 2011 Share Posted April 27, 2011 CO2 jets are a pretty standard trade show item see Plasa show. They use a HUGE amount of CO2 and cost a lot, they have to be fed with liquid CO2 which makes supplies a little more difficult. We've used Cojets and a bespoke fixed jet (for Wizard of Oz) and we own a couple of Cirrus Low Smokes (donated by The Effects Co - the picture on their website is from one of our shows). Liquid extraction CO2 cylinders are readily available from your local BOC or Air Products depot, and they deliver and collect by arrangement. It's not that expensive, and it doesn't evaporate like dry ice, so you can order in bulk in a single delivery (we used about 40 cylinders for a 20 performance run) Cold burn/freezing and asphyxiation hazards must, of course, be consdidered. We put CO2 monitors in the pit at muso waiste height, but we've never got them into the red. Link to comment Share on other sites More sharing options...
