Electric slime

Marvin and Milo Jan 16

What you need

Cornflour
A tablespoon
A cup
Putty
Vegetable oil
Polystyrene or a balloon

Instructions

Mix two to three tablespoons of cornflour with vegetable oil in the cup to make a gloopy, slime-like thick cream.

Rub the polystyrene or balloon on your hair.

Make a stream with the slime by pouring it from the tablespoon back into the cup. Wave the polystyrene object or balloon near the slime stream. The slime should move towards the balloon and become much thicker.

Results and explanation

The slime is made of tiny particles of starch surrounded by oil. Rubbing the object makes it negatively charged and it attracts the positive ends of the starch particles so that these line up and clump together.
