Instructions

Fill the cup or tray up with water and place it in the freezer. You can also use ice cubes from your freezer and skip this step.

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

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.

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.

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