Awesome applesauce oobleck for fall learning. Fall is an excellent time of the year to put a little twist on classic science experiments. That’s how we decided to try this fun applesauce oobleck recipe. Making oobleck or goop is easy with just 2 main ingredients.



Learning how to make oobleck is one of the easiest science experiments you can do on a small budget with kids of all ages, and in a class setting or at home. I love how versatile our main Dr Seuss oobleck recipe truly is and it provides a neat science lesson along with great tactile sensory play!

This applesauce oobleck recipe below adds to the senses with the smell of cinnamon and apples. Perfect for your fall activities with kids, fall lesson plans, or a preschool fall theme! We’ve got you covered with this oobleck activity, or rather you will be covered with oobleck!


Kids love themed activities for the different seasons and holidays and it’s a great way to reinforce similar concepts while still having fun. Oobleck can be done in so many ways!



Oobleck is usually a mixture of cornstarch and water. Roughly a 2:1 ratio but you can tinker with the ratio to find the desired consistency that still maintains the properties of oobleck.

What’s the science of oobleck? Well, it’s solid. No, wait it’s a liquid! Wait again, it’s both! Very fascinating to be exact. Pick up solid chunks,  pack it into a ball and watch it ooze into a liquid. This is called a non-newtonian fluid, a substance that acts like both a liquid and a solid. Read more here!


This slimy strange mixture got its name from one of our favorite Dr Seuss books called Bartholomew and the Oobleck. Definitely take the book out of the library or purchase a copy to go along with this fun sensory science activity!

  • 1+ cups of apple sauce
  • 2+ cups of cornstarch
  • bowl and spoon for mixing
  • cookie tray or pie plate for experimenting
  • cinnamon spice if desired


1: Start by adding cornstarch to the bowl. I always recommend having extra cornstarch on hand for experimentation with ratios of cornstarch to liquid or if the kids accidentally add too much liquid.

Oobleck is very forgiving! You will just end up with a larger amount in the end!

2: Next, add the applesauce and get ready to mix. This can be messy and your hands may be easier than a spoon. Start with 1 cup of applesauce first and then add more water as needed.

3: (optional) Add a sprinkle of cinnamon for an apple pie theme!

If you add too much cornstarch, go ahead and add back in some water and vice versa. I highly suggest making small changes at a time. A little can go a long way once you start incorporating it into the mixture.

Your oobleck should be neither soupy and runny or too stiff and dry!

Can you pick up a clump but then it oozes back into the bowl? Yes? Then you have a good oobleck on your hands!


Oobleck is truly fun for kids to help make too! It’s completely borax-free and non-toxic. Not tasty but taste-safe just in case someone sneaks in a nibble. Below you will see my young son helping make the oobleck. He’s added 5 years now!



I really wanted to show him the science behind apple oobleck since it is so cool that it can act like a liquid and a solid. I was hoping that if I showed him all about it and experimented with it so he could see it, he might be interested enough to touch it and I was right!

Go ahead and explore the sense of touch, smell, and sight! Can you hear oobleck? Although this oobleck recipe is non-toxic and borax-free, it won’t be tasty to eat.

Note: I kept our oobleck a bit firmer with extra cornstarch. This made it a bit less slimy though it still illustrated the properties of a Non-Newtonian fluid!



Oobleck is a fun substance made from a mixture of cornstarch and water. It’s a bit messy too!

A mixture is a material made up of two or more substances to form a new material which is our oobleck! Kids can also explore liquids and solids which are states of matter.

Here you are combining a liquid and a solid, but the mixture doesn’t become one or the other. Hmmm…

What do the kids think?

A solid has its own shape whereas a liquid will take the shape of the container it is put into. Oobleck is a bit of both! That’s why oobleck is called a non-Newtonian fluid.

A non-Newtonian fluid is neither a liquid nor a solid but a bit of both! You can pick up a clump of the substance like a solid and then watch it ooze back into the bowl like a liquid.

Make sure to try this! You can form it into a ball even! Touch the surface of the oobleck in the bowl lightly. It will feel firm and solid. If you apply more pressure,  your fingers will sink into it like a liquid.

Oobleck is so fascinating for such a simple and inexpensive science activity.

  1. That is too cool! Can’t wait to try it! I love the fact LO can do the mixing! I’m such a stickler for measurements I don’t usually let her do much around my playdough batches. I’m getting there 😉 TY

  2. How much does the recipe make? We are making this for our apple rotations this week and will need enough for 170 first graders. We are thinking about doing groups of 4, would this recipe be enough for all 4 kids in each group?

  3. What a great idea! I love making cinnamon Christmas ornaments, and I’ll be that, once you’re done with this dough, instead of throwing it out, you could keep adding cinnamon until it is stiff and then let your creations dry out! No waste!

  4. In an effort to be a nutritionally purposeful child care center and sensitive to the fact that not all centers/families can afford to “waste” food we have decided not to make any food based crafts.

  5. Very understandable! We have a terrific list of non food sensory bin fillers you might enjoy. We also offer a variety of apple themed ideas that do and DO NOT use real apples. Maybe the oobleck would be nice made the traditional way with a sprinkle of cinnamon to ignite the senses!
