Sodium Amalgam (Mercury is so cool)
Category: Inorganic
Mercury dissolves many metals. Put a little on normally steadfast aluminum and it will slowly eat it away. Mix it with some silver, copper, and other metals, and you've got a dental filling. Mix it with sodium, and you've got...

Didymium (Yes, I just ran through a list of rare earth alloys)
Category: Inorganic
The term "rare earth metal" is a misnomer that's just stuck around. They haven't been rare for years - take this ad material from about 50 years ago at Theodore Gray's excellent Periodic Table Table site....

British Anti-Lewisite (Sometimes the common name is just too cool to pass up)
Category: Medicine
Lewisite is nasty stuff, which I'll cover tomorrow. Tonight, it's an antidote, which is simply the dithio analogue of glycerine. It enjoys the more colorful name of BAL, or British Anti-Lewisite....

Thiophene (Sulfur, not quite stinky)
Category: Synthesis
My boss was, generally, far from cavalier about chemical hazards, but his quips were the best. "You'll get hit by a bus before this stuff gets you." "We all have to go sometime!"
