The internet has been stunned by a mind-bending optical illusion where a man bounces a ball to and from himself using a mirror.
The viral video shows Kevin Parry from Oregon throwing a ball to himself sparking debate online how it can be possible, the Daily Mail reports.
The mesmerising footage begins with Kevin wearing a white shirt in the bathroom at his family home in Portland, Oregon. He grips a green bouncy ball in one hand while filming himself in the mirror with his phone. Then for an enthralling trick Kevin throws the ball against the mirror and films as his reflection catches it. The illusion is created that he is bouncing the ball to and from himself in a parallel universe.
Online commenters are unable to offer any kind of explanation about how the trick works.
