I am not expecting to punch through Titanium. I just want to do something different. And if it doesn't work then I can build a normal flipper.

To calc the pressure I am using a converter to go from 16 Bar to 1.6 N/mm^2. From that its (25 x Pi) Squared... oh darn it... I hate using the calculator on my PC. Right... (25 x 25) x Pi = 1963.49 mm2, which gives a total of 320.4kg on a point at 16 Bar.

And the yield strength of Ti 5 is 950MPa. Ok, that is a little impossible. Oh the up side HDPE's is only about 30MPa so Explosion is in trouble.

Does anyone know what cylinder Heatwave used? It looks very similar to the one we have.

Also, can someone give me the dimensions of a 20oz Paintball CO2 tank.
