Make a 3D holographic projector with your phone, tablet or TV: 
Holographic projection is nothing but a projection of an image on a transparent object. The object could be water, mist or something similar. In these videos below, we bring you a few methods where the image is not projected, but reflected off a transparent glossy surface, such as an acrylic sheet or glass, to create a 3D floating holographic object.
