Here's a close up of the copper. I wish the shine would show through in the photo. I didn't have time to get more of the rock off but perhaps I will later. Mr. Thomas is just the best and I hope he knows how much I appreciate him letting me use the lab for this. I also hope he knows how much it means to me that I was able to go on the trip with his class. It really was so much fun and I enjoyed going and gaining more knowledge. Well, I guess I had better go off and curl up with my Chemistry book *sigh*. Wish it were the needles.
