IMPORTANT rules to follow when handling dry ice: thermal winter gloves and goggles should be worn at all times.
Necessities for the following activities: a cooler to hold the dry ice while prepping the activities, a package of dry ice (can usually be found in the cooler section of stores), liquid dishwashing soap, a pitcher of warm water, a large bowl, juice, glasses, pennies, and a hammer.
Experiment #1: Soapy bubbles of dry ice- Place a large piece of dry ice in a bowl (make sure those gloves are on when touching the ice), pour liquid soap onto the ice, then pour warm water into the bowl.
You will see a wonderful bubbly froth forming. Do not touch unless you have thermal gloves on!
Did I mention the snow gloves? They are important if you touch ANY of the ice mixture, you will get a freeze burn which is not a pleasant thing! Dry ice can be as cold as -110 degrees!
Experiment #2: Carbonated juice– add a tiny centimeter square of dry ice to juice, don’t drink until all the dry ice has dissolved.
Experiment #3: Break pennies- Put pennies directly on the ice for about 10 minutes, remove and hit with a hammer. Goggles would really be a good idea here, you don’t want small pieces of pennies flying into your eye. 😉
