Describe what happened

The colour on the skittles in the petri dish slowly dissolved heading towards the middle colouring the water. The colours were separated which made it look like a pattern.

Why did the colour move the way it did?

Because of the shape of the skittle.When sugar is moved into water it heads towards the middle. The colour comes out of the skittle and slowly spread out.
