i've heard they are a science experiment.

i googled it once to see the chemistry behind it. I'm not a heavy hunter, but I've found a couple.
 

ya its called "magic pennies" we sold them to kids at our annual engineering week in school from the chemical engineering booth....neat little trick and we lit the lab on fire once or twice !
