I got another way to do it. Take ammonium nitrate and nitromethane and mix them together, then put about 3 fluid ounces of it into a pan, and put the pan into a bunsen burner.

also, iJasc is right. drano is very dangerous when you try to mess with it. It doesn't just have sodium hydroxide in it. I think there is Chlorine in solution too, along with other nasty stuff. I've seen what happens when you try to titrate Drano--bad idea.

I've done this before. The silver pennies are just pennies with a super-thin layer of zinc deposited on them from the zinc-sodium hydroxide solution. The gold happens when you heat the penny and the copper creates an alloy with the zinc(brass) and looks golden. Remember that the layer of brass is very thin and relatively delicate. If you leave them with a layer of zinc it is even more so. Try using a clear nail polish or something to coat the outside when you're done to preserve the finish.

I'd like to try that actually - but i'm not going to run out to get those chemicals just to turn a penny gold. Plus they're pretty useless once you've done that.

Man, why is everyonje being so skeptica? Weather or not it is usefull or real is irrelevent, because it is still cool. This site is for when you are bored, not when you are tryin to get rich. Just enjoy it.

Could the silver penny be mistaken for a dime if no one pays attention?
