The ideal effect to go with our Bible Coloring Books. You open and show a box of crayons, with many beautiful colors. Then close the box and lay it on a table or have a spectator hold it. Open the box of crayons again and they have vanished, only to find the Coloring Book now in full color. The box of crayons has many other uses. If nothing else, having the crayons just vanish is real magic. The crayon box is self-working. We even made our own crayons, which won’t melt. If you’ve never done a magic trick before, you can do this!
