Hey everyone, my band is gearing up for next summer's tour we are looking into a few show production ideas. So i need help. We are very interested in learning more in those CO2 shooters that you see at some rock shows. I know Skillet uses them alot. We are very interested in getting those our selves but since we are independant, it's much more work so we are trying to find the source of these. Are they actually CO2? Also any of you have any other sweet show ideas. (Already tried the rotating drum riser...nope.)
