Introduction: How to Make an Air Powered Explosion Simulator
This video demonstrates a simple design I came up with for safely simulating an explosion, such as what might be used in special effects. The most valuable piece of information this video demonstrates is probably how to modify a sprinkler valve, which is useful for all sorts of air powered projects. One problem that might arise in the valve modification is that the hose fitting threaded into the top might leak around the threads, in which case some epoxy can be applied around the fitting on the inside of the valve housing which should seal it pretty securely.
I may do a follow up project to show all the other things this device can be modified to do, so stay tuned!
