Interactive Optical Illusion Experiments

Optical illusions trick us into thinking we're seeing things we're really not seeing. Objects seem to shrink and grow, and sometimes disappear! With the same index of refraction as vegetable oil, our Disappearing Beaker is a simple, but very effective illusion. The Optical Illusion Card Deck includes a different optical illusion on every card... that's more than 52 illusions (including jokers).
