This is one of my oldest creations... PVC pipe with a balloon at one end and some duct tape just for strength. It'll launch anything that'll fit down the pipe!
How does it work
Well first, you must pop the bb in the gun, and second of all, you must pull the balloon back and release, to make the gun, follow the pictures
Demo video. I mean do I wanna build this if its not that powerful?
This might be me missing something but...um... how does it work?
I'm assuming you dropit into the baloon and use it like a slingshot?
Fun and easy! Thanks!
