I feel like the schematic is pretty worthless. I thought the picture was mislabeled because the schematic shows the chamber about the size of a two liter bottle, but the picture points towards a ~3' long tube only a few inches in diameter. That, and the nozzle is considerably thicker than the pressure chamber and the diagram shows it as being smaller. I wish I could see an actual schematic (unless they're concealing the design) because this thing is pretty cool and I really would like some details. Imagine what a racquet ball could do in this kind of design (I'm only kidding).
- rtkwe 14y agoIf you read the article you'd have found out more about the device. Specifically the tube is about 12 ft long. The actual dimensions of the pressure chamber isn't really important here it's the design of the nozzle. Which they do have a proper schematic for as it happens: http://www.gizmag.com/how-to-build-a-supersonic-ping-pong-gun/26082/pictures#5 http://www.gizmag.com/how-to-build-a-supersonic-ping-pong-gu...
- tmh88j 14y agoThe size and shape of the pressure chamber are important as they determine the escape velocity of the air into the nozzle, especially if it relies on a scavenging type effect (which it may judging by the vacuum line in front)
