For this project, the pre-k students became magicians. They spent class creating magic potions to help them practice their color mixing skills. The first ingredient for their potions was milk. Each student had a shallow dish filled about ¼ full. Next, drops of liquid watercolor paint were added. To make the magic happen, they each receive a wand with our last secret ingredient on the tip: liquid dish soap. When their wand touched the milk, it made the colors visually explode. The chemical reaction that happens on the surface of the milk makes the liquid watercolor move around in a tie-dye type way. The more they moved their wands around, the more the colors mixed.
