PVC Air Jet
Warning: It should also be understood that the use of plastic water pipe (PVC, ABS, or any other) for pneumatics is not suggested by the manufacture. Accidents are very rare however, as most people follow generally accepted safe practices through proper solvent welding, do not pressurize the pneumatics above 100 PSI, low environmental temperatures (below freezing) also makes plastic pipe far more brittle, so accidents happen more frequently in colder air, and you take full responsibility for your actions when working with pneumatics.
This is a mini version of what we used in 2002 to scare guest in the sewer. These are more suited to mount into a wall and shoot a puff of air at the guest, and a lot easer to work with then the big one. The air jet is simple to make and all the part can be found at a local hardware store for around $20. The design is simple and easy modified to accommodate a larger chamber and valve for better performance. You can also add an adapter to the output for a smaller nossle to give a more powerfull & directed blast.
