We used to break thermometers and put the mercury in a tiny dish. Then we’d coat pennies and dimes with it, several times, until it was all used up.
And we’d coat the lead ends of .22cal LR rounds and fire ‘em thru my old 1958 Mossberg 144LS (still have it in pristine condition).

That was good for a few days entertainment.
Didn’t kill me, or my 50s grade school buddies (yet).
