Fun with Oobleck

This project/experiment meets many parents dreams. It is a learning experiment. It's fun. It's easy to make. It will keep your kids occupied for a long time! What is it? It's Oobleck!!!!

My science methods teacher made this with the class when I was in college. We had tons of fun with it and then when I brought it home, my husband couldn't quit playing with the Oobleck either.

Items to collect:


measuring cups

1 cup of dry cornstarch

large bowl or pan

green food coloring

½ cup of water


1. Cover your table or counter with newspaper.

2. Put the cornstarch into the bowl or pan. Add a few drops of food coloring.

3. Add the water slowly, while mixing.

4. Continue to add water until all of the oobleck feels like a liquid when you’re mixing it.

5. You will know that you have the perfect consistency when you can tap on the surface of the oobleck and it feels like a solid. If it seems too powdery, add a bit more water. If it seems too wet, add more cornstarch.

6. Play and experiment.

Thanks to 5 Minutes for Mom guest writer, Tara Rison, for reminding me about this fun stuff today. Tara also has a website, The Itty-Bitty Bookworm.

I love Oobleck! I use to introduce science at the beginning of each school year using this activity. The kids do love it.
