HOW TO – Make a pocket-sized water bottle launcher

Captain Pedantic shows you how to make a pocket-sized water bottle launcher – “There are plenty of bottle rocket plans out there, but I hadn’t seen anyone use a quick release coupler as a launch mechanism before. Plus, all other launchers are so large, it seemed to me all you need is the coupler and a valve. I decided to make two so me and the girl can go to the park and have a shootout (after all, the bike pump is hers).”Link.
