Watch dancing cornflour!

When cornflour is mixed with water, it becomes a goo that flows like a liquid until it is hit or pressed – then it acts like a solid. Watch the video below to find out what happens if cornflour is placed on a speaker that is vibrating and making sound waves.

The cornflour goo is getting continually hit by the vibrating speaker, making these weird and wonderful dancing cornflour figures!

This cornflour and water mixture is sometimes called oobleck, and you should definitely try playing with it at home! Here’s a recipe for how to make this slime-like substance…

You will need:
Mixing bowl
Spoon
Cornflour or custard powder
Water
Food colouring (optional)

What you do:
1. Place four heaped tablespoons of cornflour or custard powder into a bowl.
2. Add a splash of water and stir the mixture. Keep adding water a little at a time, until the mixture is about the same consistency as honey.
3. If you add too much water, add some more cornflour or custard powder.
4. Add a little food colouring if you like and mix it in.

Watch the video to find out more about the strange properties of this special substance.
