Instructions

1. In a bowl, combine the corn starch and cold water.
2. Mix until the corn starch has dissolved.
3. In an empty ice cube tray, put a few drops of food coloring in each cube. Have fun making different color combinations!
4. Pour the corn starch/water mixture into a measuring cup so it's easy to pour into the ice cube tray.
5. Fill the cubes about 80% full. The mixture will make enough to fill one ice cube tray of 14 cubes.
6. Use a toothpick to stir the color up if desired.
7. Place ice cube tray in freezer for approximately 3 hours (times will vary).
8. Pop the cubes out and color sidewalks for some awesome summer fun!
