Penny for Your Thoughts

In my chemistry class we did a mini-lab on surface tension. We placed a penny on the table and used a pipette to place drops of water on it until the bead that formed finally broke.

I still don't remember why it did that... had something to do with electronegativity and hydrogen bonds, but as far as specifics go, your guess is as good as mine.

At any rate, I liked the lab so much that when I got home from small groups tonight I pulled out my camera and repeated it. I got some pretty neat shots, too.

I wonder if I could get class credit for this?
