I worked night shift in a metal fabrication shop about 11 years ago.

Two bastions of humanity figured out that they could light an oxyfuel torch and adjust it to a neutral flame, snuff the flame out of a glove or something, and then use the torch to fill a plastic sandwich bag with a perfect mixture of oxygen and acetylene. They would then place this bag somewhere and light it on fire, which made a lot of noise. They had great fun until they tried it with a small office-sized trash bag. The word of the day is brisance. It made a tremendous bang which cracked some glass in the shop, but of course our two heroes were caught in the blast amd burned, because a sandwich bag made a loud pop, but a trash bag was more of a bomb. They lit the trash bag like they did the little bags, by holding a lighter to the plastic.
