Optical Illusions

Optical illusions trick us into thinking we're seeing things we're really not seeing. Objects seem to shrink and grow, and sometimes disappear! The amazing Optical Illusion Ring seems to grow or shrink simply by turning it. With the same index of refraction as vegetable oil, our Disappearing Beaker is a simple, but very effective illusion. Take the Illusion Spinner for a spin and see your hand shrink or grow as if bugs are crawling under your skin; see colors magically appear from a black and white pattern; or watch kaleidoscopic patterns emerge under fluorescent light!
