A strange and interesting phenomenon that can be observed thusly:

  1. Stand in an average sized doorway
  2. Place your arms down the side of your body
  3. Move your arms outwards so the back of your hands are pushing into the sides of the doorway
  4. Push as hard as you can against the doorframe in your current position for a few minutes
  5. Step back from the doorframe and discover your newfound floating arms
