My husband brought home some dry ice to play with.

Things to do with dry ice:
- put in in water
- watch it bubble and smoke
- make howling ghost noises over the smoke
- wave your hands and blow at the smoke
- color the water
- put things in to see if they float or sink
- put in baking soda to see if it "explodes" (it didn't)
- touch the freezing glass bowl
