Building a CO2 water cannon without a tank?
Posted: Mon Sep 07, 2009 12:00 am
Hi guys,
quick question...
I go to Thailand every year for the worlds biggest water fight (see http://dsphotographic.com/g2/thailand/S ... terfights/ ), and I am trying to put together a killer watergun.
The concept needs to be ultraportable, powerful, tankless and pumpless.
Through reading, i've kind of gotten the idea that this can be done, but I didnt see any build plans for a gun that uses CO2 to draw a stream from a pool of standing water through a venturi, and pressurize it out of a nozzle, instead of just using Co2 to build up pressure in a tank.
The concept in my head works the same as an off-the-shelf power washer, but replacing the electrical pump with a Co2 source to build pressure.
During songkran, there's tons of 50 gallon buckets all over the road full of water for people to refill their water guns. I'd like to just be able to stick a 6 foot hose inside of it, blast away, than run down the street and do it again at a different water source.
Can anyone suggest a built plan for such an ultimate weapon, or any other suggestions on something that would work for a citywide water war? Everyone else in town uses supersoakers and dipsticks, and i'd really like to see a bit more technology on my side this year for the carnage.
Can this be done?
Thanks in advance everyone, happy hunting!
