Suggested Family Activity • HomeMade Gak
To make your own homemade gak, all you need is water, cornstarch, and food coloring (if you want to color it). Combine the water and cornstarch in a bowl and mix it together until smooth. Stir in drops of food coloring a few at a time until you reach the color you want. And that’s it! Just store it in an air-tight container if you want to keep it.
