Line all of the skittles colors (except green) around the inside edge of the plate. A white plate works best so kids can see the full effect of the experiment.
Using the green Skittles, make a shamrock shape in the center of the plate.
Pour HOT water onto the plate very slowly. Use just enough water to coat the bottom of the skittles – about ¼ way up.
Sit back and watch the magic happen!!!
