Fun with Sulfur Hexafluoride
Lugoj, Romania

Martin, our current CouchSurfing host, has got himself setup with some blazing fast Internet in his home (inside an eyesore of a gray concrete communist bloc apartment building). After working so damn hard in Biharkeresztes to get sporadic Internet access, our cup runs over with convenient access to his wireless router.

Checking e-mail, I came across this awesome piece of knowledge, courtesy of Mythbusters:

Just as inhaling helium raises the perceived pitch of your voice, doing the same with sulfur hexafluoride will lower it. Check out the great video:

Interestingly, this is what the encyclopedia on my laptop has to say about it:

Sulfur hexafluoride, a human-made chemical, is one of the most potentially destructive greenhouse gases ever produced. This synthetic gas compound has nearly 24,000 times the warming effect of an equal amount of carbon dioxide over a period of 100 years. It is an exceptionally stable gas with an estimated lifespan of 3,200 years once it is released in the atmosphere. Sulfur hexafluoride is used as insulation for high-voltage electrical equipment and in the production and casting of magnesium.
