Enrichment Activity for 5-11 11-14


What you need

  • Ground pepper
  • Ground salt
  • Balloon

Instructions

  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.

These experiments have not been specifically safety tested for home use but we believe them to be safe if the instructions are followed. Adult supervision or direction is recommended as appropriate. All experiments are carried out at your own risk.
