Blow up a Balloon with Dry Ice

PIRA: 4C40.15

Materials: Balloon, Dry Ice

This demo will show how dry ice sublimates and the gas that it produces will slowly blow up a balloon. This is done by putting a few pieces of dry ice in a balloon then tying it off. After a bit of time, the balloon will inflate by the trapped gases being produced by the sublimating Carbon Dioxide.
