Optical illusions can easily trick the brain, no matter how hard you try to avoid them. One viral illusion that confused the internet shows six girls sitting on a couch — but only five pairs of legs are visible.
According to experts, optical illusions happen when the brain misinterprets what the eyes see. In this photo, many people were left wondering where the “missing” legs went.
Reddit users eventually solved the mystery, explaining that one girl’s legs are hidden behind another’s, creating the illusion that a pair of legs is missing. The overlapping positions and angles make the image look impossible at first glance, turning it into a perfect brain teaser.
