My uncle did this with trash bags. Big boom.

  I did as well (50:50 with oxygen), ignited with a shot from a roman candle. Close enough to knock me over when I was 14. Realized how fucking stupid it was when I thought about static electricity and trash bags....

    > static electricity My dad did bag bombs in his twenties. He was worried about them exploding while he handeled them, so he put on wool mittens to protect the hands...

  My chemistry teacher did this with hydrogen and oxygen inside of the classroom. It was one of those "desk waste basket" trash bags rather than a proper 50-galloner but even so it was so loud I was surprised the windows didn't blow out. I think she stuck with party balloons for that demonstration from then on.
