Sunset in a Glass

Posted 2015-02-21 by carlyfollow
Experiment with the causes of colour by creating your own sunset in a glass.



Time: 5 minutes
Age: Any age
Level: Easy



Materials
  • A glass
  • Water
  • Milk
  • A torch

  • Method
  • Find a dark space to conduct this experiment.

  • Half fill the glass with water, shine the torch through the water. Note the clear and white colours showing.



  • Add some milk and explain how milk contains proteins and fat molecules. There are particles in the liquid. Just as our atmosphere is full of billions of particles.



  • How will shining light through particles differ from shining through clear water? Use the torch to find out.

  • Shine the torch through the glass in different angles and directions. Can you spot the colours of the sunset?




  • Extend on this experiment by trying various shaped glasses, and different ratios of water and milk.
