PhysicsFun 720 - The Wild Eyes Holographic Glasses
Wild Eyes Holographic Glasses: put on these goggles and on top of every point-source of light will appear an animated holographic image of sharks swimming. (Here I used a Maglite flashlight with the cap removed.) The "lenses" in these glasses are actually transmission holograms with the image located at the farthest point in the depth of field. In this version there are three holographic images in a trifocal glasses arrangement- tilting one's head brings the animation to life! Holographic glasses can also be used to project an image using the beam of a laser- the very same technology used to make the "projection caps" on inexpensive laser pointers. Made by American Paper Optics LLC.
Physics describes the real magic of the universe.
