Potato cannon with a kick, 160mm chamber to 75mm barrel.

!THINK SAFETY and DONT POINT AT PEOPLE! USE EYE, EAR AND HAND PROTECTION. This is a test of my 160 mm to 75 mm pp potato cannon some time ago. the first shot is with a cabbage head the second shot is with a l cola tin can (full with cola) and the third with a bottle full of sand.) not a great video but, the 2 first shots arent that bad :) Its a combustion cannon that i use hairspray as gas\gunpowder.
