How Does It Work? Step 1 - Place the stand on a flat surface, about 1 foot away from a blank wall or window. The front of the stand must face the surface you wish to cast a shadow on. Step 2 - Place the Jersey Devil shadow caster into the front slot of the stand. Step 3 - Place a tea light candle (included!) within the round opening of the stand and light it Step 4 - Make your surroundings as dark as possible and see JD appear!
