Before-and-after hands sketches

Some of our illusions are designed to give people the (very real) perception of having a hand that is very different to how it is normally.

We asked people to draw how their hands felt before and after some of our illusions.

Which of the following can you identify here?

  • An extra hand
  • A super-long finger
  • An extra finger
  • A missing hand
  • An invisible hand
  • A melting hand

In each image, "Before" is pictured left, and "After" is on the right.
