Trick your mind with this clever device


  1. Square of card
  2. 2 short lengths of string
  3. Tape
  4. Pen/pencil


  • On one side of the card draw a cage, and on the other draw a stick figure, bird or other drawing.
  • Poke a hole half way down each side
  • Poke the end of each piece of string through the holes, and tape in place
  • Holding the string between thumb and finger, roll your fingers back and forth to make the card spin


The man looks like he’s in the cage.
