This Optical Illusion Is Breaking the Internet — Six Girls, Five Pairs of Legs… What?!

A new optical illusion is driving the internet wild: a photo of six girls sitting on a couch—but only five pairs of legs can be seen. The puzzling image, shared on Reddit, has sparked a wave of confusion and debate as viewers try to figure out whose legs have “vanished.”

Experts say illusions like this happen when the brain and eyes get out of sync. According to the Queensland Brain Institute, the brain often fills in missing details too quickly, creating a false interpretation of what we’re seeing.

In this case, clever positioning and overlapping bodies create the impression that one girl is missing her legs entirely. It’s another reminder that sometimes our brains are the best illusionists of all.
