Hey guys. I recently had a standard kitchen sized extinguisher drop and break its cap. I thought this could be a good time to build a fun homemade airgun. I can figure out safe working pressures and all that but as far as the design I'm stuck between a couple ideas, how have you guys built them in the past? I'm not trying to give any limitations on ideas. If you have an idea on making a cork gun I would be interested. Or a 177 plinker or a soda can launcher for all I car. Just trying to do something fun and skill building. Even better if my little girl might be able to fire it. Thanks I know I'm not the only one who does dumb poop just for kicks around here.
