Ha ha, Holy crap!
^^^^getta load of this guy!^^^^ Forget about your safety, that's almost not fair to your neighbors. Your homeowners insurer would probably be interested to know that as well.
Ummm... don't do that anymore. I'm always safe "to taste" as well, alarms go off when i know somethings kinda dangerous, and i take appropriate measures.. but there's nothing you can really do to make that safe. And realistically, there is no excuse to do flash in that size batch with that method. I believe static, friction ect. are all multiplied as the mass increases, blah blah blah; do whatever you want, i just hope to god there are no children (or anyone for that matter) around or in the house when that goes down.
Oh yeah sorry for the double posting a few days back, my computer is super 'tarded sometimes, i clicked on the post button and got nothin, did it again, ect.. didn't even think it went through.
