Few safety precautions:

Before attempting any of these science experiments, please make sure that your kids put on safety glasses, gloves, etc, especially with experiments dealing with dry ice. Dry ice must not be touched by bare hands nor it should be placed on the skin. Also, be very careful with experiments that involve fire. Keep fire extinguisher and a bucket of cold water at hand, while doing any experiments with fire. The best way is to not to let your kids do any fire experiments. Instead, you show the experiments yourself.
