30 years ago I was a teenager a friend of mine had a giant plot of empty land in his family, and so we'd go out there and do stupid teenager things things like playing with fireworks and building and shooting potato cannons.

We'd discovered dry ice bombs alongside internet plans for potato cannons, and in our infinite wisdom we tried to build a dry ice bomb powered potato cannon. In our mind the sudden increase of air pressure would've sent the payload going ridiculously far.

Thankfully when we went to use it the first time, we were smart enough to run as far as we could before it went off. It was far far more pressure than the pipe could handle and it sent little bits of PVC shrapnel flying everywhere.
