How to make spooky oobleck for Halloween

Make spooky oobleck using only simple household ingredients in our fun Halloween spooky science experiment.

Please note - this activity will require adult supervision!

The science bit:

Everyone knows that there are three states of matter: solid, liquid and gas.

Right? Well actually no! Oobleck is a type of material known as a non-Newtonian fluid, meaning that it is neither a liquid nor a solid, and most definitely not a gas.

Unlike water, for example, which changes state due to changes in temperature, oobleck reacts to changes in pressure.

If you quickly apply pressure to the oobleck by hitting or tapping it, it will feel like a solid, but if you scoop it up in your hands it will behave just like a liquid and run through your fingers.

How spooky is that?
