- Green Food Colouring
- Mixing Bowl
Put half a cup of cornflour in the mixing bowl and add a quarter of a cup of water
Add a few drops of green food colouring. It could really be any colour you like, but green is more ghoulish!
Give it a good mix - you might need to get your hands in there!
Once it's made, squeeze it and it'll turn solid...
...Open your hands and it's back to liquid! Weird!
