<p>[QUOTE="Just Carl, post: 93726, member: 4552"]The things I've done to coins for fun is almost a little too weird. Like most kids living around railroad tracks we all just had to put pennies on the tracks and see if a freight or passanger would make a difference. Drill holes in coins to make a charm for a girl. Melt different ones together with an arc welder. Put coins in a tree trunk and shoot 22's at them. Bury them in concrete building walls or floor for some future gerenation, Make things like pen holders out of liquid plastic with coins embedded in them. Give $100 woth of pennies in beer cans to a couple for a wedding gift. Actually tried throwing a silver dollar across a river. One of our presidents tried that I think. Every sidewalk near my house has at least one penny in there somewhere. However, the most fun I've had was in college chem lab with melting copper pennies in sulfuric acid, collecting the CuSO4 crystals after boiling off the solution, adding it to distilled water, filtering and allowing the water to evaporate under controlled temperatures to form one large crystal. Hope there weren't any 55DD in there.[/QUOTE]</p><p><br /></p>
