Did you ever drop an M-80 mud ball in a topless 55gal barrel of water?
We put them under empty 5 gallon buckets to see how far they’d launch. It was actually pretty impressive.
No mud balls though, never saw or heard of that.
I had a buddy in high school with an arc welder and acetylene torch. On 4th of July one year they got around to taking hefty trash bags and putting them under 40 gallon or so metal garbage can, filling the bag with acetylene and setting the welder contacts under it. Then they’d go into the garage and turn the welder on, nearly sending the can into low earth orbit with a window rattling boom and a resounding crash when it came back down to earth...
Never tried that. I blew up a soup can once and had a piece of shrapnel go by my head 100 feet away.
My best M-80 story was a few years ago. One of my neighbors asked me to light her gas grill. She was scared to do it because a friends grill had just blown up.
So, being the nice neighbor, I went to my house to get matches (and an M-80) On her back porch, I leaned my head into the grill, lit teh M-80 and tossed it to the side on the ground. Just then, my neighbor came onto her porch.
BOOOOM! followed by me screaming and holding my face in my hands.
She screamed then yelled at me.
THey moved not long after. I’m not sure why.
