Gloopy oobleck!

In our study of liquids and solids we found a substance that can't decide what it is!
Gloopy oobleck is made from cornflour and water and is great fun to play with - but can make an awful mess!
We rolled it into balls and it was solid but when we stopped rolling it, it became a liquid! It felt solid when we punched it and liquid when we pushed it. We really enjoyed experimenting with it. You can add food colouring to it too if you want coloured gloop.

This is what happens when you stop rolling it!

  1. This looks like a whole lot of fun. It also explains why Louise came home with cornflour all over the front of her hoody! Caroline (Louise's mum)
