A former coworker of mine, when he was a kid, once used his father's oxy-acetylene rig to fill a plastic garbage bag with both acetylene and oxygen - in his basement. He planned to take it outside and light it at a distance. As ge was trying to close it off by gathering up the neck of the bag, a static spark set it off. He was very lucky - his only injuries were a burst eardrum and large areas of petechia (bleeding under the skin due to many ruptured capilaries) on his thighs. The blast ripped his pants. He did manage to have kids himself later on :) On Oct 14, 2018 3:31 PM, "John Ferrell" wrote: I would be banned for life if I told you what 10 year old boys did with it in 1950, On 10/14/2018 1:56 AM, RussellMc wrote: > Deep-ends how much air is mixed with it. > "SOME" air included here. > Stoichiometric mix utterly not recommended. > Don't try this at home > YMMV / Your mileage may vary: --=20 John Ferrell W8CCW Julian NC 27283 It is better to walk alone, than with a crowd going the wrong direction. --Diane Grant --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
