- Large Glass of Water
- Ice Cubes
- Put an ice cube into your glass of water.
- Place a large pinch of salt on top of the ice cube.
- Lay the string across the top of the ice cube.
- Place more salt on top of the string.
- Wait 3 minutes.
- Try lifting the ice cube out of the water with the string
- The string is attached to the ice cube!!
The salt melts the ice and leaves a ‘pocket’ of water on top of the ice cube. The pocket refreezes around the string!
