How Do You Safely Use Dry Ice?
Though dry ice is a great addition to any Halloween party, it should be used with caution. Dry Ice should never be consumed! Don’t put it directly in your punch and NEVER touch it with bare hands. To make dry ice steam: Place dry ice in a suitable container. Then pour hot water over it and stir with a wooden spoon. Dry ice will last for up to eight hours in the refrigerator, but will only steam for about five minutes after water is added. So plan your ta da time carefully.
