Andy -
Not familiar with it. I assume it's a noise maker as it uses propane.
Let me tell you of a friend who picked up one of the tank cannon simulators that fired using propane. He had a ball! They were asked for the parade to come up with something with more noise than the black powder so they used the simulator. The crowd loved it! When he got home his wife showed him the mirror - blood coming from ears, eyes mouth. Propane is what it's cracked up to be.
FWIW. Have fun and be safe & legal.
