DANGEROUS DEMO! Can't get liquid nitrogen? Then make your own version by using Dry Ice. Note that this demonstration involves several major safety hazards, and should only be performed by skilled professionals.

Note that dry ice comes from companies listed in your local yellow pages. Some welder supply stores carry it. In Seattle, you can find it in the seafood section of QFC neighborhood grocery.
