Using the Aquadoodle Classic Color mat is super easy. First, fill the Aquadoodle pen with ordinary tap water. Then, run the pen's nib over the magic mat, and you'll see colors appear right away. You don't have to worry about any mess because the water that runs off is clear and won't stain anything. As the drawing dries, the designs will fade, and you can start all over again. When you run out of water in the pen, just refill it. There are shapes and characters around the edges of the mat to copy, and hidden letters and numbers inside to trace. Try to combine them into a story for more fun. When you're finished playing, fold up the mat for easy storage. Remember, additional Aquapens are sold separately if you need more.
