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.

I wish we did stuff like this at school.

*goes to look for spare pennies*

We did that in 8th grade!

DUDE, I did that in my freshman science class. I think I still have it in an old purse somewhere.

Seventh grade for me. ^_^ I actually did it in an afterschool advanced chemistry program. I remember that day clearly because that was the day I surprised the hell out of myself by knowing "aurum" was Latin for "gold" and that's why the chemical symbol for gold is Au.

I wish that I had been able to do stuff like that in my chem class. We only got to put copper into a solution and watch it turn into silver though and mix sodium and water. Which now reminds me of Kimbly. Freaky. That would have been neat to do. I want to get into silver electroplating eventually because I'm a totally jewelry making nut.

Whoa, hey, I did the same thing! Well, no, not really, it was different and we used pre-1982 pennies... and it was brass that the outside turned into... but that's not the point. :D It was still fun.

I did that expierment a long time ago my Sophmore year of high school. Lots of fun. I might still have the penny somewhere.

I'm giving this to my teacher. x)

*copies this to give to his CP 11th grade Chem class ^____^*

my favorite experiment last year. we had so much fun XD
who do you have as a teacher?
Megmegkips on September 21st, 2005 12:22 am (UTC)
Ms Carr. I really like her, she's a real sweetheart.

My friend's Chemistry teacher did this and he has a bunch of them. They really look like gold too!
(how interesting, I'm wearing my red FMA shirt right now. o.O)

We did that in my AP Chemistry class last year! I breathed in the fumes, though :x

Good times ^^

I remeber doing that last year in Chemistry! such horrible horrile times those were...
Saya: Targetedsayahiei on September 21st, 2005 04:03 am (UTC)
I did that for Summer School, it was one of the only units I listened to because it had to do with alchemy....I burnt my hand about 5 freaking times on the penny!

i wish i could this... all i get is stupid atom bonding in chemistry :(

My schools sure did suck. Not once did I get to try anything like this. :( Although reading all of that scientific stuff made my head spin. @_o;
