Learn how to make oobleck with two ingredients. This recipe is easy to make and a super fun sensory play material for kids.

Oobleck is a non Newtonian fluid ––it changes from a solid to a liquid––which makes it a very engaging sensory play material for kids.

Since it’s one of those sensory play materials that you’re making from scratch and know exactly what’s in it, this material is fun even for older babies and toddlers to explore.

A note about the mess

This sensory play material is super messy so we recommend pouring it in a bin…and taking it outside! If your kids do play with this inside, try putting it into a sensory table or bin with a floor covering underneath it. Or take it to the bathtub for extra easy clean up!
