I will start by saying that I have never made oobleck before. Therefore, I began by doing what everyone else does when looking for information and searched on Pinterest. As a result of my search for oobleck recipes, I came across the blog, Little Bins for Little Hands, and their post called, Evergreen Oobleck Science Winter Sensory Play.

Their oobleck was perfect! So, I decided to recreate it and add a few things of our own. If you haven’t checked out their blog yet, please do. They have lots of great ideas for STEM activities, especially slime.

In our household, we absolutely LOVE sensory play! I have been wanting to try oobleck before, but never have. Now was the perfect opportunity.

Making oobleck is a fun STEM science experiment. It is an object that is both solid and liquid. Have you played with oobleck before? If not, I highly recommend it.

Oobleck Recipe

1 cup of Cornstarch

1/2 cup of Water

The instructions are very simple. All you need to do is mix the cornstarch and water together. I used a pie pan for this activity.

SUPPLIES

Pine Branches

Pinecones

Cranberries

Pie Pan

Spoon

Optional: Beans and/or Wood Blocks

On Ben’s little craft table, I set out the pie pan with the oobleck along with the pine branches, a bowl of cranberries, and some pinecones.

INVITATION TO PLAY

At first, Ben just experimented with touching the oobleck. He wasn’t quite sure what to do with it. Then he started adding cranberries and pinecones.

He loved watching the cranberries sink into the goop. He also liked pushing the pinecones into the oobleck and pulling them out.

Next, he involved a spoon. He tried to scoop the cranberries out of the oobleck. He discovered that it was hard to do. I also encouraged him to put his hands into the goop.

He tried pushing on the oobleck with his fist and found out that he had resistance. Solid. He also scooped some up with his hand and watched it drizzle between his fingers. Liquid.

As with any open-ended sensory play, Ben decided that we needed more materials to experiment with. He started by adding some wood blocks.

He discovered that if he pushed the end of the wood blocks into the oobleck that it would help support them. Then the building commenced.

Last, but not least, he added black beans to the pie pan. He had a blast trying to get them out of the oobleck. This was great for his fine motor skills.

As you can see, Ben had a great time exploring his winter oobleck sensory play. For being the first time ever making oobleck, it was super easy and simple to make and led to lots of fun. I am encouraging you to try this activity with your little ones. Happy Exploring!

As I said before, please check out the blog, Little Bins for Little Hands. It is full of great content. I want to thank them for sharing this activity on Pinterest. We had so fun fun recreating it!
