Illusion

Green Dragon

You can make this illusion of a dragon out of paper.

  1. Download the net.
  2. Print a copy of the net. A colour printout is best.
  3. Make up the dragon model.
  4. Stand the completed model on a window ledge or table.

When you move around, the dragon's head seems to follow you around the room. Have a look at the video, to see what we mean.

How does it work? If we move around when viewing a solid object, our brain knows how the object we are looking at should behave. However the dragon gives us the wrong clues, because we misinterpret what its shape is. We assume that the nose of the dragon is pointing out towards us, but in fact the dragon's head is concave.

That's magic!
