Now, if you have plenty of CO2, then it really doesn't matter how long you leave the valve open. We found that when we left the valve open for a full 1 sec, the sound our canon made was quite satisfyingly resonant. Almost like a big BUuUuURRRPP.
One thing we've noticed is that our regulator becomes 'frozen' from the CO2 after 4 or 5 t-shirts. Usually we just wait for it to thaw and then we're good to go again. The CO2 tank is massive, not sure how many shots we'll get but it will be quite a few.
