Right outside my back yard is the sixteenth green of neighborhood. My next door neighbor and I went outside last year with an oxygen/acetylene bomb.
Basically you take cutting torches and get the mixture the same as you would to cut steel. Then you take an empty trash bag (making sure there is not static electricity present

) and fill it with the gas from the torch nozzle. Tie the bag off and make a fuse, in this case we taped a long strip of paper towels to the bag.
We filled a fifty five gallon bag full

and set it in one of the Sand traps next to the green. Lit the towels and ran like hell to go inside his house.
When it went off about 100yds away, talk about loud, we could feel the windows vibrate and see the ceiling tiles get sucked up from the frames they rested on. You could see a large fire ball going up into the sky easily for a couple of hundred feet. There were car alarms going off and people coming out of their houses, which we did too playing dumb. :laugh:
When I went out to the sand trap the next day the crater was only six inches deep,but it blasted sand everywhere.
