You will need
● An earbud
● Food colouring (different colours)
● Glass of milk
● Bowl
● Dishwashing liquid
What to do
Pour the glass of milk into an empty bowl and add a few drops of food colouring (use a mixture of colours). Take the earbud and place a small amount of dishwashing liquid onto the bud. Place this earbud into the milk.
What to look out for
When the earbud with dishwashing liquid is submerged into the milk, the milk begins to move causing the food colouring to mix. The fats in the milk are interacting with the soap, this is causing observed movement. Remove the earbud and submerged it in a different spot in the milk, the reaction will be observed. Continue doing this and explore the different hypnotic patterns made by the milk and the food colouring.
