How to make Goo

You know how much I love goo ( or gloop ), so when we collected lots of pinecones, sticks and leaves yesterday, I couldn’t resist making goo with an Autumnal feel.

Little H helped me make it this time. We didn’t measure it out, just added water slowly. She loved the sticky feel of it and kept letting the goo run down from her fingers.

As always the DUPLO people got involved and very messy with us.

This is such a great sensory activity for little ones, H doesn’t understand the science behind the way the goo feels, but she got so much out of just being left to explore and play by herself. It was lovely to watch.


Who would you add to your goo?

The Science Bit

Did you notice that if you make a ball with the goo it is solid, but if you drop it on the floor it turns liquid again? The goo is a non – Newtonian fluid as it doesn’t flow like liquids normally do.

The goo is made up of molecules arranged in long chains. When the chains are stretched the liquid will flow, but when you force them together they stick together to form a solid.
