2-Ingredient Oobleck Recipe

Step 1

While it will take a little experimentation to get the proper consistency, a good starting place is to mix 1 1/2 cups of cornstarch with 1 cup of water. I added 3 tablespoons of green tempera paint to color the suspension, but you can use more or less or leave it out altogether.

Step 2

Mix the ingredients using your hands, adding more cornstarch or water as necessary. Note that you may need to use more cornstarch if you live at a high altitude. You’ll know you’ve got the right consistency when it feels similar to honey or molasses, yet “tears” when you drag your fingers across the surface.

Step 3

Store the oobleck in a covered container to play with again. The cornstarch and water may separate, but you just simply need to work them back together.
