I always assumed that the process of making a hologram was so complex that it was limited to only those with access to expensive lasers and other fancy optical equipment. But when I heard that the Maker Shed started carrying Litiholo’s Hologram Kit, I was surprised that such a thing existed and I was eager to give it a try. After carefully following the directions, my first hologram was visible, but just barely. This was better than I expected, actually. The manual stresses that controlling vibration is the most important factor in creating a good hologram, but I live in a busy Brooklyn apartment building that often feels the low rumble of the subway trains rolling by. I tried to make another, but this time I increased the exposure time from five minutes to fifteen as the instructions suggested. The result was a surprisingly sharp hologram of a toy car.

The science behind the why holograms work and how they’re made is fascinating. In the video above, I explain that the holographic film is sensitive to the interference between the laser beam hitting the plate directly and the beam bouncing off the object. I won’t try to explain it any further, and I’ll leave it up to those who do it best: How Stuff Works has a great write-up of the principles behind these amazing 3D images.
