Just saw a Bud commercial with the song "Summertime." I really like that song, but then I realized...it's 21 years old. :eek: Wow, college was a long time ago.

I know, but it's titanium :D
Did you know that titanium is significantly more abundant in the Earth's crust than copper or zinc? Get a penny. Now, that's special. :D

(Btw, I didn't know until a couple of minutes ago that pennies minted after 1982 are 97.5% zinc and 2.5% copper.)

Yup. I've done this before: scratch a penny to expose the zinc, soak in HCl solution, eventually you will be left with a copper shell that looks like a penny, or scratch all around the edge and get 2 peices. Google it.
