Turn brass pennies into gold.
I was never very good at chemistry at school. Or physics. I'm a writing kind of guy. So I'm always in awe when I see the real power of science at work, before my very eyes. And seeing alchemy work (or look like it works anyway) is a real bonus. This clip shows you how to turn ordinary brass pennies into silver, and then, GOLD.
I have no clue of the science involved here. I'm sure it just turns nice little brass pennies into nice, gold colored brass pennies. And as yet, they aren't quite legal tender anywhere. So don't go changing all your dollar bills into pennies, dumping them in chemicals and then hauling them off to the bank, having first given your boss the finger. I suspect all these are good for is something nice to display somewhere, or a fun way to impress kids at parties. Anyway, be careful with your vats of chemicals, and have fun.
