RE the 18" of pipe--good question. When you mount a bottle half full of water on the launcher a bit of water trickles into the pipe. If the air pump hooked in right at the bottom of the launcher, the water will collect there and could back up into the pump--making it very hard to pump. Tire valves have a check valve (one way valve) but they often leak a little. Including that empty 18" of pipe bellow the valve lets the water pool there harmlessly. Slater
@pyroman675 At the end of part 6 at 1:50 it shows how to tape on the leftover 22 inch piece of pipe, both to keep the spring on and so the pipe doesn't flop. Slater
@robert0joe re:using primer on PVC pipe before using the cement. It's a good question. I never use primer, but I do scuff up the surfaces to be cemented a little. I've never had one leak. Slater
@pyroman675 Do you mean the launcher is tall? The whole point is to get it overhead so the bottle can't hit somebody on the way up (people rush in to get wet). Valve from any auto parts store. Slater
Go to an auto parts store and get some cheap, common, pull-through stems. Long or short stem does not matter, but if there are two widths get the thinner. Slater
