1. Half fill a petri dish with water.
2. Carefully place 4 differently coloured skittles evenly spaced around the outside of the petri dish.
Hypothesis I think that the skittles colours are going to swirl in together.
the skittles are made of sugar and food colouring. As the sugar dissolves the food colouring moves over the water with sugar until it cannot move any further because of the other colours.
