Oobleck is a super cool science experiment that both kids and adults absolutely love. It’s a weird substance that when you grab it is solid but when you let it go, it falls out like a liquid. After testing many variations of this recipe, I finally got the correct ration to get perfect Oobleck every time! ‘
Follow along, print the recipe and I’ll even show you how to make it and how I set it up for playtime. By the time you read this post, you will have all the tools needed to set up a successful oobleck activity at home or at school.

Sensory play can be a lot of fun and it offers a lot of educational opportunities for your little ones. Oobleck Recipe is a fun way to explore sensory play.
During the fall season, we are always looking for ideas to do at home or at the park with our friends that can offer some educational opportunities.
Last week, I hosted an event with the local mamas and shared with them the opportunity to teach their little ones through play as a demo to my new sensory classes.
We explored the theme apples and we made oobleck as I called the event “messy play apple pie”. I have also made this activity with a melted pumpkin theme and an ocean theme. Follow along so you can get inspired!
I’m totally obsessed with this Oobleck Recipe and I want to share with you how to make it.
“Oobleck is a non-newtonian fluid. That is, it acts like a liquid when being poured, but like a solid when a force is acting on it. You can grab it and then it will ooze out of your hands. Make enough of this oobleck recipe and you can even walk on it!”

This stuff is know as “oobleck,” named after a sticky green goo in Dr. Seuss’ Bartholomew and the Oobleck. Scientists, on the other hand, refer to cornstarch and water as a “non-Newtonian fluid” — a material that appears thicker or thinner depending on how it is physically manipulated.
Notes
If your oobleck is too hard and not dissolving when you press with your hand and then quickly let go, then add more water.
If the oobleck is too loose and doesn’t harden when you press it with your hands add more cornstarch.
We use this Cornstarch brand for our recipes – available on Amazon or at your local grocery store.
Ingredients
- 4 cups cornstarch
- 2 cup water
- Food coloring
Instructions
- In a bowl, measure 4 cups of cornstarch
- Add 2 cups of water into the cornstarch and mix until all cornstarch has been absorbed.
- Your oobleck is ready when you can grab it and press the mixture in your hand and it’s a hard solid, and when you let it go it quickly dissolves.

How to clean up Oobleck?
Do not – I repeat – do not throw this down the drain when you are done. It can clock your drain!! Instead, throw away the loose water in the drain as you have your water turned on. The rest (the cornstarch) can be scraped off and thrown in a trash can.
Can You Make Oobleck with Flour?
You definitely can make oobleck with flour. But not just regular flour. You need flours that have starch as that is the component that will make a Newtonian fluids.
You need to look for cornflour and add equal parts cornflour to hot water. (Note: cornflour and corn flour are different. Make sure you get the first one)
Tomake oobleck without cornstarch, mix together 1 part room-temperature water with 2 parts arrowroot powder or tapioca flour.

A word on Sensory play
Sensory play is super important for little ones to explore. Just make sure you prepare the area first so that clean us is easier on you! Have a disposable table cover underneath your bin and throw it out after. Wash any clothes immediately as the oobleck will stick to clothing.
Oobleck as Toddler Science Experiment
Oobleck can be used to teach science, after all what happens with this liquid – or solid- is a chemical reaction. We certainly did over on our science week and since this fell over in October we mixed with Halloween. The result? A melted pumpkin!

I always love to create our toddler events around something to learn about. Oobleck recipe has a lot of teachings on its own as toddler’s very first science experiment, but to make it more conceptual, we used the opportunity to talk about apples. After all, we called our event MESSY APPLE PIE!
We worked on learning about a fruit we see everywhere during this time of year: Apples. What colors they are, how they feel, how they smell, how they taste.
This apple sensory activity allowed us to work on:
- Language development and vocabulary (we practice how to say a- a- apple)
- Messy Play and its importance for babies and toddlers
- An opportunity to play and bond with your little one as moms let loose in a messy controlled environment.

During the event, we did two apple-themed messy activities to explore different textures. We worked with red-colored oatmeal and green Oobleck. Both, a representation of our red apples and green apples.
