Stringy Water

Enrichment Activity for 5-11 11-14


What you need

  • A jug of water
  • About 50cm of string
  • A basin or sink

Instructions

  1. Tie the string around the handle of the jug and pull it across the top and over the lip
  2. Hold the string tight at an angle, below the jug, and begin to pour

Results and Explanation

The water flows along the string. The friction between the string and the water slows down the flow, pulling the water to the string and making it stick to it. Try creating an amazing route for the water by holding the string at different angles, even getting the water to turn corners as it goes down. But be careful, no sharp turns or the water falls off!
