Smart Mom, the sound of the one near me reminded me of a small balloon my Dad once filled with oxygen and acetylene, placed in a paper bag and lit. It would have broken all the windows in the house.
Oh, I love oxygen/acetylene ballons :D
Been playing with that stuff for years.
When I lived in Cal my brother and I filled a 55 gallon plastic trash bag with it, and another bag of helium and taped them together.
Then I taped about 12 feet of cannon fuse to the gas bag, lit it and let er go.
HOLY HELL Batman.
I never knew that town had that many cops and firetrucks in it.:D
They were everywhere for about two hours.
I had a friend call from 13 blocks down town and said his dishes were all rattling in the cupboards.
When it went off you could see a huge concusion wave in the air spreading out from the ignition point.
That stuff can be really dangerous, especially in an inclosed area.
