Electric Seasoning

Enrichment Activity for 5-11 11-14

What you need

  • Ground pepper
  • Ground salt
  • Balloon


  1. Rub the balloon on your hair or a jumper and then hold it about 2cm above the pile of salt and pepper.

Results and Explanation

Rubbing the balloon makes it negatively charged and both the salt and pepper are attracted to it. However, the pepper grains are lighter than the salt, so it is the pepper that leaps towards the balloon.
