A top that can seemingly defy gravity by abusing precession and magnetism!

This demo is quite picky, and the weight rings have to calibrated to be within 0.1 g of the required weight such that the magnet won't be pulled down by gravity but will have enough mass to sustain precession in the magnetic field. Get the top spinning on the plastic lift plate and slowly lift it off the magnetic base. If everything is fine, the top should slowly lift itself and continue spinning suspended in the air. The manual has a helpful flowchart but here are the key helpful points: - If the top doesn't lift itself, reduce the mass. - If the top lifts off but flies away, raise the leg closest to where it flew off. Adding mass might also help. Updated on 05/30/13
