Haha, take that, eyeballs!
Ball Rolls Up Slide Optical Illusion

This is an optical illusion of a ball appearing to roll up a little slide. Of course it isn’t actually rolling up a slide because it isn’t magic, it’s just a clever perspective trick (revealed in video). Me? I love playing tricks on my eyes. I also love playing tricks on my girlfriend. Like yesterday when I heard her pull into the driveway and pretended I was dead on the kitchen floor! She stepped right over me and made a salad.
