Using the Discovery Art Projector is easy. First, grab one of the 10 reusable clear colouring discs included in the set. Use the 6 coloured markers (colours may vary) to draw or write whatever you like on the disc. Once you're done, place the disc on the projector's lamp. Turn on the projector, and your creation will be projected onto the ceiling or wall. You can use multiple discs to layer your artwork for a more unique effect. Draw related designs on different discs and stack them on the lamp. When you're finished, put the markers back in the built - in caddy on the base of the projector to keep them organized. Keep the discs clean by gently wiping them with a soft cloth. Avoid using harsh chemicals on the projector and discs. Store the projector in a cool, dry place when not in use to ensure its long - term performance.
