This rattleback model is very spectacular. The inversion motion of the spinning direction is by far the fastest and the most confusing of any other kind you may find. I invented this type of rattleback with joinery to augment its atypical motion. The results have surpassed all my expectations.  The behaviour of this object really seems to go against the laws of physics.
