If you’ve been following along, you’ve noticed by now how essential toys are to our culture’s story. And here it is again, a tale of how science influenced toys, which influenced the creation of moving pictures. In Optical Toys, part of the new permanent exhibits at The National Museum of Toys and Miniatures, visitors explore the 1820s discovery of persistence of vision. Scientists theorized that the human eye remembers an image for a fraction of a second after it disappears. Thus, if two images are moving rapidly, the mind blends them into one image. Caught on yet?!

While this was only part of how the mind perceives movement, it set in motion (see what we did there?) the exploration of how the mind explores action and depth through optical toys. Think View Masters, stereoscopes, and kaleidoscopes. In the center of it all is a giant zoetrope showing one of our favorite toys taking flight. Through the use of fast moving picture strips viewed through a slot (think of it like a flip book), our now permanently grounded plane is able to soar the skies.
