Carrying on with our ‘states of matter’ topic, we have been thinking about matter that could be a little more difficult to categorise as a solid, liquid or gas. To show such difficulties, we made some oobleck! We had great fun watching how it became a solid under pressure, but a liquid when left to pour.

If you wanted to make some at home, simply mix a cup of cornflour with 3/4 of a cup of water.
