Foil Float

At home for 5-11 11-14


What you need

  • Bucket
  • Foil
  • Water

Instructions

  1. Fill up a bucket with water.
  2. Scrunch one piece of foil in the air and put it in the bucket.
  3. Scrunch the other one underwater.

Results and Explanation

One piece of foil will sink and the other will float.

The piece of foil scrunched above water traps some of the air, which helps it to float.

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.
