This is a simple experiment that might work for some people. There is some   
   nuance to it depending on the health of your vestibular system. Mine is no   
   longer working  and suffer from oscillopsia. I mention something about a ufo   
   along with other pretty    
   wild sounding claims, and I am well aware of that, but it was my experience   
   back in 1985. I'm not a scientist so there's no discussion about particles or   
   math, only some observations of phenomena. I'll leave the theorizing to others   
   trained in the field.    
   I should have documented it with a video at the time, but due to other   
   problems in life, that didn't happen.   
      
   The experiment requires a glass ball, "crystal ball" used as a second mass in   
   addition to the experimenter. I used a 150mm approximately 9 lb (4Kg) ball. I   
   call it the "human rotary experiment". There is a sequence to the experiment   
   that has to be    
   followed or else I am fairly certain it will fail. It also needs to be   
   performed on solid ground - no basements or crawlspaces below. Perhaps there's   
   a chance that someone may be able to reproduce the phenomena.     
      
   Proceed at your own risk. Should you consider giving it a try, I would suggest   
   surrounding the area with cushioned gym or exercise mats in case you loose   
   balance and take a fall. Also provide a carpet and additional rug to prevent   
   breakage in the event    
   you should drop the ball, which may occur in one mode of the experiment.   
      
   It involves first rotating yourself and the ball held in your right hand   
   somewhat away from your waist, in the CCW direction (as viewed from above) and   
   after several revolutions, reverse the ball's rotation by passing it hand to   
   hand around waist in the    
   opposite direction of your own rotation, forming an orbit close to your waist.   
   But do not bring the ball to zero velocity WRT earth. Allow slow CCW orbit of   
   ball WRT earth. More detailed instructions at link below.
