Dry ice, originally uploaded by tilak.dutta.

It's 10am and -21 outside (-29 with wind chill). I biked to work today. I was bundled up with goggles and even a scarf. Anything below -20 deserves a scarf or "muffler" as my parents say. The picture is from last week when Tonya brought home some dry ice from the lab. The temperature of dry ice is -78.5 according to wikipedia.
