COOL Eye Trick: See the Purkinje Tree!

Okay follow my instructions to see this really cool eye trick discovered in the year 1823 It's called the Purkinje tree And to do it you take your phone and you turn on the flashlight of your phone turn off the room lights and then close your eyes and put that light against your lid at the corner of your eye and then jiggle it a little bit And when you do that you're going to see the reflections of your own blood vessels and it looks like a tree And that's called the Purkinje tree
