Good idea hadent thought of it but how much pressure are you able to put it under.

man my parents are parenoid too. For my first few launches they made me duck behind a piece of wood. But I'm using sch.40 pressure rated like 150 psi and I'm using hairspray, so....

anyway, that is a nice little gun, but I'd put a barrel on it

Disposable camera and expandable foam; very clever. I'm just using an electric grill ignitor.

This is a very noob filled post.... Guys this is a COMBUSTION CANNON!! thats why there is screws in the chamber and thats why "how much pressure can you put in it doesnt really make sense!"

Nice Cannon... that is a good idea..
Good job using the camera ignition

Nice job! Definately a cool looking gun, looks like you could fit in a scuba or similar tank (nobody correct me, 'cause I know it wont fit) to make it look more uniform. I like the foam insulation idea as well. Spudzinger
