How Many Fingers?

What you need

  • A friend

What you do

  1. Place your left hand against your friend's right hand, palm and fingers touching.
  2. Take the finger and thumb of your other hand in a pincher action and stroke both your index finger and your friend's index finger with your thumb and finger respectively.
  3. Be weirded out.

What's going on?

If two people join their opposite hands and one slides his index and thumb over two joined fingers he will feel the other finger like it was one of his. This is all Planet SciCast's top researchers have been able to find about why this weird phenomenon, it's from a wiki on the web. So if you know more than us, please, use you fingers and get in touch scicast@nesta.org.uk
