method:
1. 1/2 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 all the colours are gonna go into the middle then they will mix to a different colour
scientific reasoning:
the skittles are made wit sugar and and food colour. As the sugar dissolve the food colouring move over the water with sugar until it cannot move any further because of the other colour
