My friend came to me with an idea of a pneumatic potato cannon and I couldn't get over it. I'm a huge pussy when it comes to explosives near me since I heard about some guy blowing his nuts off after he put to much propane in his PC and shot it off between his legs. So I though a pneumatic one would kick ass.
I found this site on how to make one

But before I spend some moolah building one, I wanted to know if anyone else has had any experiance in this field. My buddie claims it can put a golf ball through a fridge door at 150 ft, but im not to sure about that. Some feedback on how well they work, how safe they are, and how hard they are to build and other stuff like that would kick ass.
