These Smell and Learn Water Magic Activity Books are perfect for travel days in the car or on the plane. Fill the brush with water and apply it to the scene boards to watch the colors magically appear! Let it dry for 5 minutes and you can do it over and over again. The brush is scented to match the theme of the book too! It's no-mess activity to end the question, "Are we there yet?" Each has 4 Water Magic scene boards per scent.
