The Physics of Tippe-Top Inversion: https://www.physicsfunshop.com/search?keywords=tippe Spinning things often have surprising physics! This video is from a segment of my talk presented at PhysicsCon 2020 (Caltech’s Feynman Lecture Hall, Jan 4) where I discussed tops and other physics toys. In brief: friction with the surface provides a torque that acts on the existing angular momentum of the top to flip it over. The top will stay flipped until the spin rate slows down enough to where its center
