Age Group: 3rd-5th grade

Total time: 30 minutes

Supplies

• Small paper cups or an ice cube tray

• Glass or bowl of water

• String (yarn or kite sting works great)

• Small stick

• Salt

Directions

1. Fill the cups, bowl or tray up with water and place it in the freezer to make ice cubes. You can also use ice cubes from your freezer and skip this step.

2. When the water is frozen, remove the ice from the cup or tray.

3. Put the ice in the glass or bowl of water. The cube will bob up and down in the water and then float on the top.

4. Create your fishing pole by tying the string to the stick.

5. Place one end of the string from the fishing pole on top of the ice cube and sprinkle salt on the ice where the string is touching. Watch as the water melts slightly and refreezes.

6. After about 10 seconds, carefully lift the ice cube out of the water with the fishing pole. You caught a fish (ice)!
