Growing up in a climate where -20 degree temperatures are a normal (though generally unwelcomed) occurrence and -40 degree temperatures aren't unheard of, I'd always heard that if throw boiling water into the air on a cold enough day it will freeze or evaporate before it hits the ground. Somehow, I'd never tried it before. This video was made both for my own amusement and to document for my friends in less hostile climates that I'm not just crazy. I woke up early and discovered that it was -30 degrees, but by the time I headed outside with my pot of boiling water the temperature had dipped to -35 degrees.

Check out this 3d printer from the Fab@Home project. I want one! Did he say you could "print" in chocolate? Mmm...I wonder what some hobbyist confectioner could think to do with that?
