Key item features

  • Stress-Relieving Ellipsoid: The PhiTOP is an ellipsoid spinning top designed to provide stress relief.
  • Spinning Mechanism: Users spin the solid aluminum top by placing a thumb on one side of the long axis and an index finger on the opposite side.
  • Included Mirror: It comes with a 3.5-inch mirror for optimal spinning and observation.
  • Upright Standing: With practice, the PhiTOP can amazingly stand up on one end, demonstrating unique physics.
  • Electrodynamic Demonstrations: Although non-magnetic, bringing a magnet near the spinning PhiTOP causes it to fall, illustrating Lenz's law.
  • Optical Lissajous: As the PhiTOP settles, reflected lights create beautiful, time-varying Lissajous figures.
