I love precious metals. Right now I have silver, platinum, gold, palladium, ruthenium and iridium at home. Iridium kicks ass, it's soo damn heavy. I think I'm going to get more of it. I recently thought I would run out of iridium which I needed for a project I was working on. Until I weighted it. It looked like an estimated 4-5 grams or so, but actually it was over 30grams (sub-micron sized powder) in that tiny bottle it was stored in. Fucking cool stuff. I want more.
