Real Alchemy You can do in Science Class!  
Today in my science class we did a really neat experiment based off the alchemical writings of the arabic alchemist Jabir Ibn Hayyan. In the experiment you can change a copper penny into a penny that's coated in a gold-like substance. The final result is

:D If any of you guys end up trying this, much luck to you. It's a pretty fun experiment.

(I was a total dork and wore my red FMA shirt with the flamel on the back. No one seemed to get the symbol though.)

Note: This was done in a CP Chemistry class in 11th grade.

Heh. Simple electroplating experiment, but fun nonetheless.

*wonders where her hoard of gold pennies is*

Have you tried a pre 1982 penny? ;) You might see how that changes the experiment.

We use a 1979 and 1969 penny after we finished the first one (the one I posted). They took a very long time to change on the hotplate.

Mmmhm. There is less copper in a post 1982 penny and what makes the penny the bright gold color is the fact that you are making brass. Brass and bronze are both made from zinc and copper but brass is a bright golden color while bronze is duller. Because there is so much more copper in the pre 1982 pennies, it is more like a bronze.

I did it also with a piece of pure copper which turned even more bronze than the pre 1982 penny. *thinks* You gonna study batteries soon? Or is this just a beginning of the year fun thing?

Did you preserve the bronze or are you going to see how long it lasts? (One of my pennies is still around today...it's been forever since I've done this experiment.)

Thanks for the info. I thought it was something like that, but I wasn't 100% sure.

I think we get to batteries a lot later in the year. This was a bit of an introduction to Chemistry, examining came before the science. (Things such as alchemy.)

We laquered the coins. Mine's in my pocket at the moment. I'm gonna hang on to it for as long as I can.
