Super Expensive Metals - Periodic Table of Videos

I once had about $20,000 cash in the car with me. I was terrified.

I can't imagine how freaked out I would be picking up half a million dollars of gold much less three times value in other metals.

The Professor visits a factory refining (is that the right term? maybe it's just casting) platinum group metals (platinum, iridium, and rhodium, primarily).  The factory then processes the metals into various forms - ingots, wire, woven screens.

That's phenomenal to see.
