Valves, the difference opening time makes.

I'm fairly sure that clamping the paper will just make it do a burst disk impression.

It would be nice if we all had exactly the same type of paper to start with

[bigbob12345]

can someone try a spring loaded ball valve so we can compare it to a standard ball valve, i would but my cannon is elsewhere, and the spring is still at bunnings

I have a spring loaded ball valve gun somewhere in my garage Ill go see if I can find it

Edit:found it Ill test it in an hour or two because its really early in the morning here and nobody likes to wake there parents up
