• Clear drinking glass
  • Water
  • Full-fat milk
  • Measuring cup
  • Teaspoon
  • Flashlight
Fill a clear drinking glass with water half-way to the top.

Shine your flashlight on the glass directly over it

The water will appear white.

Now pour 1/2 cup of milk into the glass and combine well..

Bring the glass somewhere dark and shine the flashlight onto the side of the glass through the milk. 

The milk will appear yellow, orange or red
How come?
Like a sunset or sunrise, the light is shining though particles.

The atmosphere is filled with billions of particles and when the sun is low in the morning or early evening, rays travel through a thicker layer of atmosphere than at other times of the day.

When sunlight hits these particles, the light then bounces off of them and scatters.

Orange and red lights scatters the least which is why you see orange, yellow and red colours in a sunrise or sunset.
