Hydrargyrum

We're honored to hold down the Hg spot on Humbug's genius Periodic Table of Blogs.

And it's appropriate. Mercury is one bad-ass fluid:

Mercury has been known since ancient times. The origin of the name comes from the Latin word hydrargyrum meaning liquid silver. It is heavy, silver-white metal, liquid at ordinary temperatures. Stable in air and water. Unreactive with alkalis and most acids. Gives off poisonous vapour. Chronic cumulative effects.

Esp. note the last two sentences and don't say you weren't warned.
