mini burst valve cannon
Posted: Thu Feb 25, 2010 5:39 pm
I was thinking about making a small burst valve cannon.
I have some 1cm copper pipe and i desperately wish to make a new cannon.
The chamber will be about 6" long and use multiple layers of plastic bag as the disk. Think it would be worth my time building?
