Full auto ping pong cannon can be built in just a few hours

If you can’t be firing or working on real guns you may as well be turning other objects into guns.

That’s Mythbuster Adam Savage’s montra, and he’s here to show off a glorious ping pong ball machine gun.

He built the entire thing in just one day, and you can too! It will help if you have access to a lathe, otherwise you’ll just have to improvise.
