optical illusion

hey gang, hope you`re all doin' well,

in my physics class, i've learned something:


first draw this in a clean white paper:




                                  X                                                                          O




then turn your face to the left and look at the "X" with your right eye

keep the sheet close to your face and then move the paper away veeeeeeeeeery slowly, but keep looking at the X , and in a certain place, the O will disappear!!!!
how cool!
thanks for viewing, goodbye.
