How to trick your brain
An optical illusion is a picture that looks different from what is really happening. Like straight lines that look bent, or still shapes that look like they’re moving. One of our favorites is this video, where a ring of little white balls rolls around the inside of a bigger circle that’s twice as wide. It turns out that each ball moves back and forth on a totally straight line! If you don’t believe it, watch closely to see the surprise.
