Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). 1/8th speed (15fps) and improved video performance because somehow Youtube cropped the last frames of the other videos (?) I didn't quite understood the need for a razor blade but without one I still see the flow of air. For me, the razor blade just makes the dot of light smaller(?) If anyone can clarify me what the razor blade really does and where it should be placed (in the source of light or in the camera) I'd really appreciate. Also important to note that this is AWESOME to look with the naked eye but almost the dimmest light can blind you. I covered a tiny LED torch with aluminum foil and punctured a hole with a sewing needle, on the side! so that the LED doesn't bright directly through the hole. Take care with the eyes!!

Yet another poor quality video of the homemade pneumatic cannon made out of a cheap air pump for using the own piston as it works like a one way valve. Thus, you don't need to leave a small clearance for air to leak and load the main chamber. The piston let's the air flow into it, but on the shooting phase it blocks it. It's the same that happens when you pull the handle of the airpump (air enters the cylinder) and then you push it (air is NOT released, but compressed). The target in this video is the back plate of a pringles can. At 3,5-4 atm as seen here it pierces it. At 6 it goes through. At 7,5 the rear cap explodes XD And no... I'm not in undies. It's a swimming pant (summer in Spain!!) XD So please focus on the ballistics and keep YOUR mating rituals for your friends and beloved ones. Another funny fact. The rear cap explossion propelled the main body against a furniture and the aluminum cannon BENT. So poor accuracy now, but back before the accident it was kinda good...like let's say hit an apple at 15 meters (yeah, I know but I didn't want to put my eye or face close to the gun, so it surely would have been better. To the naked eye, the BB looked like flying pretty straight) Thks4watching All likes reserved
