Oobleck Sensory Play

Oobleck is easy to make using just 2 ingredients, messy and lots of fun to explore! This makes it a perfect indoor sensory play activity for toddlers and preschoolers. Older kids will love exploring the science behind how Oobleck changes from a liquid to a solid - they won't even know they are learning! Today we added penguins to our Oobleck to create a winter small world scene.

Harry (aged 4) has always loved playing with oobleck, but today it was the first time Daisy (17 months) has played with it.  She loved it!  Oobleck sensory play kept the children busy for almost an hour, making it a perfect activity to do inside on a cold, rainy winters day.

How to make oobleck

You will need: 
  • 2 cups of Cornflour (cornstarch)
  • 1 cup of Water 

This recipe really couldn't be any simpler.  Just mix the cornflour and water together.  If you want coloured oobleck add a small amount of food colouring. Add an extra sensory element by putting some oobleck in an ice cube tray in the freezer to make frozen oobleck.  

Oobleck is fascinating.  It has the properties of both a solid and a liquid depending on how much pressure you apply to it.

Today we set up a frozen small world with a winter and penguin theme. I filled 2 baking trays with oobleck. 

I added some cornflour that hadn't been mixed with water so Harry and daisy could explore the different textures.

They couldn't wait to start exploring.  Harry loved the feel of the oobleck and found it hilarious to cover me in it!

After some time exploring the oobleck and playing with the penguins in their snowy small world I introduced some frozen oobleck.  I had previously frozen some oobleck in a star ice cube tray.  I had added a few drops of blue food colouring to some of the oobleck before freezing it.

Which resulted in oobleck pouring all over the table.  Harry found it really funny to find that the tray had stuck to the oobleck on the table.

Harry asked me to freeze the tray of oobleck when he had finished his activity.  It has frozen into a sheet of oobleck ready for some more fun another day.
