Ever since I was a kid, we’ve made oobleck, a wacky combination of cornstarch and water that’s neither solid nor liquid. It’s still one of my favorite science experiments to do with kids. It’s named for the gooey substance in Bartholomew and the Oobleck, a classic Dr. Seuss book wherein a boy named Bartholomew is challenged to save his kingdom from the sticky green oobleck.
To make your own, all you need to do is combine cornstarch and water in a bowl – with a drop of food coloring to keep things interesting. Dr. Seuss’ oobleck is green, but you could make yours blue, yellow or pink – just swap your favorite color.
To make oobleck, stir together 1 1/2 cups cornstarch, 1 cup water and a drop or two of food coloring.
It’s the best kitchen science experiment to do with kids of all ages – and costs less than a dollar!
