Light bends through a lens. Bill shows us why. We call it the science of "optics." Notice that the light changes direction every time it goes from air to plastic,and then again when it goes from plastic to air. It's slows down and speeds up. When that happens, it just can't help but bend. Lean in, and have a look.
