Antigravity Maltesers

Enrichment Activity for 5-11 11-14

  • Level Elementary

What you need

  • A wine glass (narrower towards the top)
  • A Malteser

Instructions

  1. Put the Malteser on the table and place the glass over it
  2. Wiggle the glass quickly with a circular motion and the Malteser will start to climb the sides of the glass
  3. Keeping wiggling, lift the glass off the table and the Malteser will stay inside!

Results and Explanation

The glass pushes inwards on the Malteser, forcing it to move in a circle rather than a straight line. But the angle of the glass means that it also pushes upwards on the Malteser, supporting its weight.

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.
