Baby, it's Cold Outside

Colored Ice - Water Balloon Project

Fill water balloons with colored water and put them in the freezer. Watch how they've frozen into solids and go play outside with them.

What you need:

  • water balloons
  • food coloring
  • scissors

Carefully fill the balloon with water. Follow the directions on the package. (You may have to squeeze the water down into the balloon with one hand while the other hand is holding the top of the balloon against the end of the spigot (faucet). Carefully remove and tie off. Repeat. Place in plastic bag(s)* and freeze.

Leave in the freezer for 4 + hours.  Have an adult cut the balloon and the kids can peel it off. But be careful - there might be some colored liquid that falls out.

Leave ice balls on a tray and let the kids play with them.  You can also place them outside and observe what happens.  Watch the ice melt and color mix.
