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 Mystery Marbles are more than meets the eye. No matter which way you turn or tilt the tube, the three marbles will move together but they never touch
