What You Need:
- 2 cups water
- A plate
- Take 2 cups of water.
- Place about a tablespoon of salt in one of the cups, and stir.
- Place both cups in the freezer.
- Check each cup about every 10 minutes. Which one do you think will freeze first?
- Now get an ice cube out of the freezer.
- Place the ice cube on a plate and begin sprinkling salt on the ice cube. Watch how it melts… now you see why people sprinkle salt on their driveways when it snows!
