@infobeautiful When I was a kid my uncle came by with several M-80s which he set off under a coffee can, launching it pretty high in the air, maybe like the 2000 or 3000 fireworks in the video.

After a couple of times the bottom of the can was bowed out, and on the last time it separated from the rest of the can and went spinning off like some horrific razor-sharp frisbee from hell. 😂
