dry ice left over after HT.

Reminds me of olden times when the first twist off glass bottles appeared. Oh, the shrapnel flew that day I tell you!
 
My dad used to tell me stories about the things he did as a kid. He would put a chunk of calcium carbide in a glass jug with a bit of water and toss is in a lake. KABOOM! = lots of dead fish. He and his friends would go to the railroad yard and swipe sticks of dynamite and caps. (They didn't lock it up in the '20s) It was fun to set them off under a worn out train wheel. He said that they would go 50 to 75 feet in the air. Ohhhh! Lot's of fun until they would get chased away.

All I ever got to play with was black powder and M80s. Dang!:D
 
Let's not even get started on my youth.
Suffice to say, I hope kids are smarter now days. But, from that clip, maybe not.

At night a large chunk of sodium thown into a lake makes a great signal !!
 
Of course none of us ever did anything like that when we were kids. Natural selection is selective sometimes and lets a few of us by.:eek:
 
try freezing frogs, they shatter after frozen. I know for a fact it works with LIN and LOX, but maybe dry ice gets cold enough.
 
When I worked for Virginia Chemicals we occasionally got bored at night and tossed a 2# block of metallic sodium out into the river. It would skittle around like a UFO. One winter evening we took a bunch of small pieces and threw them out into the snow. They popped and hopped all over the train yard.
