The Science Behind Oobleck

Have you and your kids ever played with fireworks oobleck? It’s a non-Newtonian fluid, which means it’s both a liquid and a solid!

Other non-Newtonian fluids are slime, ketchup, and cold caramel ice cream topping. Who knew you could study viscosity, shear rate, and the continuum mechanics of physics with ketchup?! 🤯 (Ketchup becomes runnier when shaken, which is why we shake the bottle first!)

Watch this Crash Course for Kids video for a quick introduction to non-Newton fluids and oobleck.

Ingredients Needed for Fireworks Oobleck

Put the cornstarch into a large bowl or plastic tub. (We doubled the recipe and put it in a plastic storage tub.) Slowly add the water and stir until mixed together. Add a few pop rocks at a time while playing with the oobleck. Let the pop rocks explode in your hands for extra fun!

When you’ve finished playing with your oobleck, scrape it out of the bowl or tub into the trash. DO NOT PUT IT DOWN THE SINK DRAIN! It’ll clog your sink! ACK!
