How to make ice chalk

* 1 cup water

* 1/2 cup cornstarch

* Food coloring (optional)

* Ice cube trays

Instructions

1. In a large bowl, combine the water and cornstarch. Stir until the mixture is smooth and free of lumps.

2. If you want to make colored ice chalk, add a few drops of food coloring to the mixture and stir until the color is evenly distributed.

3. Pour the mixture into ice cube trays and freeze for at least 4 hours, or overnight.

4. Once the ice cubes are frozen, pop them out of the trays and use them to draw on sidewalks, driveways, or any other surface that you like.

Tips

* To make the ice chalk more durable, you can add a little bit of salt to the water before freezing.

* If you want to make the ice chalk more slippery, you can add a little bit of vegetable oil to the water before freezing.

* Have fun and be creative with your ice chalk art!
