Chest spin - Spin the hat down the arm, across the chest and out along the other arm.
Hold the hat crown down in a outside grip. Flick the wrist inwards as hard as you can so that the hat spins fast and strikes the inside of the wrist. Allow the spin of the hat to carry it across the body and along the other arm. Catch the crown as it reaches the other hand.
