Video of my Air Cannon. Pretty easy to make and a great startle scare! Thanks to Youtubers, terroronshadowway and Woodland Haunters for their helpful videos!
If you use PVC @ 100 psi your asking for nothing but trouble. When it explodes it sends shrapnel all over the place. The pipes that are used are not that expensive and can usually be purchased locally,plumbing supply, if you're really good and have the tools you can order the pipe in 20' lengths -cut to the size you want and thread the ends yourself and save a bunch of money. For safetys sake don't use PVC, use the right parts for the job.Could this be made with PVC instead of metal tubing? I would only put about 100psi through it, and using PVC would make it much cheaper. Plus it would simple and cheap to extend the tube so that the air could come out further away from the tank so I don't have to figure out how to disguise a huge yellow tank.
