Home Science Experiments: Color-Changing Milk
- A quarter plate
- Food Colour (2-3 variants)
- A cotton swab
- Liquid Detergent
WHAT TO DO
Pour some milk into the quarter plate. Now add a few drops of the food colour into the bowl, close to each other. Once this is done, take the cotton swab and dip it in the liquid detergent and then dab the swab in the middle of any of the colour drops.
There is a huge explosion of color when the swab dipped in liquid soap comes in contact with the added food color. The food color which was just a few drops when added initially, is all over the quarter plate. You see a huge fusion of colours and this continues for quite some time.
WHY THIS HAPPENS
Milk is made up of water, minerals, vitamins, proteins, and tiny droplets of fat. Soap breaks up the fat globules and weakens the chemical bonds of proteins.
Replace the milk with water and follow the same steps again. The results are not the same. Can you tell why?
