Diy Mini black powder Cannon

sry for the bad angle on the cannon but you can see it fly in the air right after it shoots. ill make a new video later, maby a night film :)
At the time when i was on my wasy to be a welder, i had the change to play a bit with a milling machine and i made this Mini Canno, its out of a solid steel rod, so it should take the force from the black powder, and it takes it like a man :D
