Refraction Demo: S**t happens

Refraction is the phenomenon that makes light bend when passing through different transparent materials due to the velocity of light changing in different media. It makes objects behind the refractive material look distorted. Refraction is useful for simulating glass, water, gemstones, and many other transparent materials. To see for yourself how refraction works, just rotate the model, paying attention to how the shell appears to distort beneath the egg white.
