I filled a cup halfway with water and halfway with oil, then set out two cups of liquid watercolor. Using eyedroppers, they drop the colored water into the oil, watch it form a little ball, and then see it dissolve once it breaks through into the water at the bottom—fascinating to watch! | Preschool Vibes | Facebook
