When I was a teenager working in the sawmill millwright shop, we used to take an oxy/acet torch and fill up a pop can with the gas. Then light the torch and touch it off. It was a hell of a bang. Then one night on graveyard shift one clown filled a garbage bag up with that gas and threw it in the burner conveyor. When it dropped in the burner it blew some of the plates off. We ran like hell.
PLEASE DON'T DO THIS because back in the 70's pop cans were tin but today they're aluminum. I forgot about that one time and I almost blew my ear drums out. I had limited hearing for about an hour. It was so powerful it blew the dust off the I-beams in the shop.
On maydays (a local celebration at the end of the yr) a local guy would do the same gas/garbage bag thing. Unfortunately for him and his girl friend one blew up in their shop and they were badly injured.

Please share stories of your dad. He sounds like my kind of poofkaboom guy.

Oh he was. Like you he got an idea in his head and it was full steam ahead. Long hours in the garage until he was successful.
Thanks for sharing things with us.

Well you've made the grenade, might as well make the grenade launcher..lol

I suggest that if any of you want to see these videos then download them to your computer.
In a week or two I'll be deleting them from Youboob. I don't want that stuff on the net, especially under my name. Note I named it a "confetti grenade" and even added paper.
There are several things that I build but do not post here. There are reasons.
I had to post it on Youboob because hoser don't let us upload videos here, probably because of hard drive space at his end.
