Things are not what they appear to be
The optical illusions shown by illusionist, skeptic and magician Jerry Andrus in this clip from Bill Nye's science show include Box Impossible, Trizone Space Warper (which causes clouds to boil), and the Nutty Bolt Bender, shown above.
"I can fool you because you're a human," said Andrus. "You have a wonderful human mind that works no different from my human mind. Usually when we're fooled, the mind hasn't made a mistake. It's come to the wrong conclusion for the right reason."
Thanks for the video find to my good friend Gregg Tobo at Astonishing Productions>>
