The PhiTOP is a very carefully designed top that counterintuitively stands up when spun in a horizontal plane, rises, and then settles down, spinning for 2-3 minutes. Besides being a COOL toy, the PhiTOP has unique observable traits in dynamics, electrodynamics, Lissajous Figures and a great illustration of the “Gelatinous Ellipsoid Effect”.
Invented by astrophysicist Kenneth Brecher, the PhiTOP encourages exploration of force, mass, density, gravity, friction, and time. This elegant scientific and aesthetically pleasing top makes a perfect gift, desktop display piece, or student challenge.
