Hologram Projector
Ages: 8+
A hologram is like a three-dimensional photograph. Photographs show only height and width. Holograms show height, width, and depth.
Creating an actual hologram using a laser is not something we usually do at home due to equipment and safety issues. However, we can create a 3D projection that looks like a hologram. In this project, we make a transparent, four-sided pyramid. The pyramid’s sides act as four mirrors, situated at 45° angles on a smartphone or tablet screen. The screen and pyramid become a hologram projector. When used with a holographic animation video, moving 3D images (holograms) appear inside the pyramid.
