Taste Safe Oobleck, Messy Play For Toddlers

Oobleck is made of ingredients you probably have in your home already: cornstarch or cornflour. Oobleck is a non-Newtonian fluid. It has properties of both: liquids and solids. You can slowly dip your hand into it like a liquid, but if you squeeze the oobleck or punch it, it will feel solid. The name oobleck comes from the Dr. Seuss book, “Bartholomew and the Oobleck.” ⁠

Materials needed:
4 cups of cornstarch
2.5 cups of water
food coloring (optional)

1. Place 4 cups of cornstarch in a bowl. If you'd like to have colored oobleck add food coloring to the water.⁠
2. Add 2.5 cups of water to the cornstarch. ⁠
3. Mix the water and cornstarch together. You can either use your hands or a metal spoon. ⁠
4. If needed, add a little more water. ⁠
