Cornflour, water, a wooden spoon, a bowl.


Step 1

Pour half a box of cornflour into a bowl. Then gradually pour water over and mix until it looks and feels like custard.

Step 2

Run your fingers through the liquid.

Step 3

Now try and punch the mixture with your fist.

Step 4

Explain the water runs away first with pressure.
Try putting a fresh egg into the middle of the cornflour mxture in a zip lock bag and dropping it to see if the egg is protected.
