Put the cornflour into a bowl with the water and food colouring and mix well.
The mixture should look watery on top, but feel hard when you push a spoon into it. When you squeeze the gloop it will turn solid. When you hold it flat in your pam, it will turn to liquid and start running through your fingers!
Spread the gloop onto a clean surface/tray and make marks through it.
