this is the old metal ball i bought at a flea market in the summer along with an antique pendulum. Unfortunately, I can't get closer with a tablet camera, there are no clear photos.can it help to use 25% of the brain potential instead of 11!? it needs chemicals as auxiliaries. the energy can coordinate the chemical events. perhaps. but no money for camera and chemistry experiments, I would like to fly with it as high as a buzzard....
