Chocolate Oobleck

Do you know what oobleck is? It’s material that’s a cross between a liquid and a solid. You can dip your hand into it, like a liquid, or you can squeeze it, like a solid! We’ve made some traditional oobleck to go along with a Dr. Seuss book, but today I’m sharing how we made chocolate oobleck!

Here’s what you need:

1/2 cup of cocoa powder
1 & 1/2 cups of corn starch
1 cup & 1 tablespoon of water (approximately)

To make this, mix 1/2 cup of cocoa powder with 1.5 cups of corn starch in a bowl. Then slowly pour in the water while you mix with a spoon. If the mixture is too watery, add in some more corn starch. If it is too dry, add in some water.

It’s so fun to play with! It’s a messy play activity, so some oobleck will stick on your fingers. We kept a bucket of warm water to dip our hands in when we wanted to clean our hands off.

Like I said earlier, oobleck is a mix between a liquid and a solid. It “moves” on the table when you let it just sit there. When you pick it up, it feels like a solid. But when you let it just sit in your hands, it runs down your fingers.

See how fun it is to play with! It is a messy play activity, so be prepared to wash hands and the table afterwards! But we love messy play at our house 🙂

Since my middle son’s favorite color is green (seriously…everything HAS to be green!), we made green oobleck, too! He couldn’t wait to dip his hands into the goo!
