Dart Cannon


Very powerfll and mobile cannon. uses a blowgun for a barrel. this thing can shoot a 1g dart at velocitys that I'm still trying calculating. With out the cannon a blowgun has velocits from 150 to 300 fps.  Impressive consitering the human lungs can put out around .5 psi. This cannon gets up to 100+ psi. You can imagin the velocity has got to be pretty fast consitering I have shot a dart threw a quarter with this one.
