me like. At least the guy they shot had protective eyewear on, although it is still never the best idea to aim a cannon at someone, especially their face.

can you re-hijack something?

is 1" the biggest sprinkler valve you can get? (I know it is the biggest I have found, I am just curious to find out)

sweet ... that is the size of Co2 cartridge you can use to inflate bike tires, right?

It will only go to the moon if you aim it in the correct direction. What was it being used for on the aircraft?

so what is the pressure in the barrel after you fire it? ... roflcopters

But you would still have to reload it, correct?

Nice piston - pretty cool for your first pneumatic cannon
