The Crayola Color Explosion Glow Board lets kids create cool designs with glowing marker inks. Using it couldn't be easier - simply draw, flip the switch and watch the creations glow. The board comes with 2 transparent drawing surfaces that slide inside the board, one on top of the other. With the 2 boards, kids can create awesome background images and simple animated scenes. Press the 2 switches to easily light up the front or back image. A 4-position slide switch allows kids to activate the lights in different configurations for lots of display options.
