How does it work?

Unfortunately, this section is only available in the e-book version of the project.

In this science experiment your right eye sees inside the tube, and your left hand sees your open hand. An optical illusion is created because your brain is confused, as very different signals are received from each of your eyes. Your brain then combines the images and you appear to see a hole in your hand.
