This recipe makes cool, non-toxic slime that appears to have a life of its own! It’s electroactive slime, so it reacts when it’s close to electrically charged objects. Rub a piece of polystyrene foam or a balloon on your hair or a wall to charge it and observe how the slime reacts.
Time Required: 30 minutes
Electroactive Slime Materials
- 3/4 c cornstarch (175 mL)
- 2 c vegetable oil (475 mL)
- glass or tumbler
- 1x6x6 inch (25x150x150 mm) styrofoam
How To Make Electroactive Slime
- Mix the cornstarch and vegetable oil together in the glass.
- Refrigerate the slime mixture until it is chilled.
- Remove from the refrigerator and stir (separation is normal).
- Allow the mixture to warm enough so that it can flow.
- Take a block of styrofoam and charge it by rubbing it on hair, wool, or a cat.
- Tip the container of slime (which should flow slowly). Place the charged styrofoam about an inch (2 cm) from the flowing slime. It should stop flowing and seem to gel!
- If you wiggle the charged styrofoam the slime may follow or pieces of it may even break off.
- When the styrofoam is removed the slime will continue to flow.
- After use, refrigerate slime in a sealed container.

Instead of using polystyrene foam, you can rub a balloon on your hair to build up a static electrical charge. The electroactive slime is attracted to the charge on the balloon.
