Me and Precision are brothers btw. Back to the subject, today i pumped it 90 times and it went through 4 sheets of card board. Also, I photo gate tested the speed of a marshmellow, it traveled .5 meters in 0.0044 seconds, which means it went 250mi/hr.
The higher the pressure the faster they go. Oh, and I just tried using dots, those things are lethal. They went through 3 pieces of cardboard and then 100 ft.
