I was the man standing behind the other man! My Johnson is going nowhere near that thing!!

Surely fig 2 is basically what i've already made, only the blow gun trigger is replaced by the ball valve!

How does one measure muzzle energy? I didn't even think of the legal aspect! Has anyone ever been arrested for making a spudgun?!

So it started as a casual bet between me and my brother as to who could build the best one. Here's mine.

It's pneumatic, this is at about 60 psi.

The valve is rather clever though I say so myself. Looks like a standard ball ...
