Dry Ice

My aunt, Priscilla, who lives in Sunnyvale, CA so generously sends us packages from Omaha Steaks with yummy steaks, burgers, twice baked potatoes, etc. It's a celebrated event in our house when the big styrofoam cooler arrives, not only for the steak, but for the dry ice!!! It's amazing how a big chunk of ice that you can't touch with your bare hands can entertain my two high-energy boys for an hour or two... :)
