Easy Tie-Dye Milk Experiment for Kids to Learn About Surface Tension Video


                                      East Tie Dye Milk Experiment

Milk has a property similar to water that is known as surface tension. The molecules in the milk that are bonding to each other create this surface tension. Soap is used to break surface tension. When soap is added to milk or water then the bonds between the molecules of the liquid are broken. In this video, an easy experiment is demonstrated to learn about surface tension by tie-dye effect.

Materials Required: –

  • A small dish
  • Whole milk
  • Food Colouring
  • Cotton buds
  • Liquid soap

Procedure: –

  • Pour the milk in the dish so that it will cover ¼ inch of the depth. Let the milk settle in the dish.
  • Now add one drop of each colour to the milk.
  • Make sure to place the drops in the center of the plate. Keep the drops close to each other.
  • Take a clean cotton bud and touch the tip of the bud to the center of milk.
  • Remember, you do not have to stir the mix. Just touch it gently with the bud.
  • Now, add a drop of liquid soap by using the other end of the bud.
  • Put the soapy end of the bud back at the centre of the milk.
  • You will see that the colours in the milk are moving in a swirl.
  • After 10-15 minutes, even if you will remove the cotton bud from the milk, the colours will keep moving.
