Rules Question

Our team would like to use CO2 as the compressed air source for a number of reasons, safety being one of them, but wonder if it is prohibited under the rules.

I cannot find a specific prohibition to the use of carbon dioxide. The rules appear to say only that the gas must be "atmospheric". CO2 is an atmospheric gas but do the rules mean that the gas must only be compressed air?

First it avoids the use of gas tanks (I think CO2 is stored like the O2 in scuba tanks) that are dangerous.
That way it´s only admited air from compressors (not scuba tanks) in WR competition.

Second CO2 is in a phased-state, it means that´s partial liquid and partial gasous, so when the gas is ejected and reduces the pressure therefore the liquid may turn to gas and starts to be ejected also.

Since there is CO2 liquid there it´s no longer a water-rocket but a water+C02 liquid rocket.
And this is a competition for water-rocket only.

NO ROCKET DOPING LOL

Compressed air in tanks is allowed under the current competition rules.

See section II for the special rules regarding bottled air.
