Oct 19, 2015 · Q1: Without table top friction, the top won’t invert. This proves that frictional forces cause the inverting effect. And when the spindle hits the tabletop, the Tippe Top jumps up to inversion - presumably due to the increased distance between the spindle top and the axis of spin. This would increase any torque effects.

Apr 19, 2018 · After watching a lecture presented by Dr Tadashi Tokieda on Toy Models , as his final demonstration (see the 55:30 mark on the linked video) he shows what is called a chiral tippe top. When spun in a clockwise direction the top behaves as if it is a normal tippe top, tipping itself over a few seconds after it is spun.
