Optical illusions: people love them because they break your brain like drugs. But unlike drugs, illusions are free, they don't show up on drug tests, and you can't overdose on them (probably). The latest illusion making people on the Internet scream with hazy delight and confusion is this video from Viner Kevin Parry where he appears to be throwing a ball to his own reflection in the mirror.

Is he the first social-media savvy sorcerer? While that would be great, the answer appears to be much more mundane, as commenter Rad Dlugowski pointed out: "There are two people," Rad noted. He continued: "You can tell because the motions of the 'reflected' phone don't match the changes in perspective of the recording phone."
