Are eyes are wonderfully designed but they can be tricked.  Try making a thaumatrope - you can use the template below or design your own.

 

thaumatrope is an optical toy that was popular in the 19th century. A disk with a picture on each side is attached to two pieces of string. When the strings are twirled quickly between the fingers the two pictures appear to blend into one due to the persistence of vision.

 

Examples of common thaumatrope pictures include a bare tree on one side of the disk, and its leaves on the other, or a bird on one side and a cage on the other. Many classic thaumatropes also included riddles or short poems, with one line on each side.

Watch this video to make a bird appear in an empty cage. https://www.youtube.com/watch?v=GSEDvR3DZ8M
