Public project summary
Scratch holograms scatter light in order to formed raise images. As noted by their name, scratch holograms are made by creating abrasions on the surface of a dark colored flat surface. These abrasions are a series of arcs. This project will focus on making these series of arcs using a laser cutter set on its engraving setting. The engraved surface will be used to make a mold. Then, dark chocolate will be poured on the mold so that the effects of scratch holograms can be seen on an edible surface.
