So what happens if you shoot a plastic garbage bag filled with acetylene and oxygen on the 4th of July?
It was just a small 13 gallon bag half filled but it had an impressive punch to it, I would say it rivaled a 1/2 pint boomer. It rattled the windows so much that after a few shots, I was asked not to do it any more. :-) It also emitted a bright flash which I was able to capture it with my digital camera in the third picture. The video was taken with the same camera also (it was before I had a DV camera) so there is no audio. My digital camera takes QuickTime files so I converted them to MPEG and then to WMV so the quality is poor.
