Color Changing Milk

Colour changing milkIs your child easily fascinated by magic? Now you can perform a little “magic” with just milk, food colouring and a drop of liquid soap and have your child go “woo” and “ahhh”!

Why this happen?
The secret to the color changing milk science experiment is the fat inside the milk. The soap molecules try to re-align and stick back together when they are put into the milk and this is what causes the fat molecules to move around dragging the food coloring with it. Basically the soap has to hook onto the fat and the motion that you witness is the result of this.


You will need:

–       Whole milk

–       Plate

–       Food colouring (a few colours)

–       Dish-washing soap detergent

–       Cotton swabs
