After finally fixing the many leaks on my pneumatic i decied to test it with water at the garage. But that soon got boring. as i was making carp fishing boilies at the time i made a barrel sized one. And charged up the cannon to 100 psi and aimed at this trolley thing with 3 layers of thick ply board then a pillow at the back. Not realised that it would go through the lot i fired and BOOM! the noise my mum came out and went livid at me. I think she may cut up my cannon so im trying to hide it which is hard because its 3ms long. has anyone else done something similar.
