• Liquid Dish Soap
• Shallow Pan/Dish
• Whole Milk (Room Temperature)
milk bottle
 
Steps
1.  Pour some milk into the pan.  Allow the milk to come to room temperature.

2.  Add a few drops of different coloured food colouring into the pan of milk.

3.  Add a few drops of liquid dish soap into the pan of milk.
