![]() Swipe to see another astonishing property of this top described in a previous post. Balanced such that the spin point was placed at its center of mass, this unique top was used by Maxwell to experimentally test many theories about how the Earth and planets wobble as they spin. After the top gets a flick from my hand note that one can see a circle of evenly changing color- the angular momentum vector points outward through the center of that circle. The four color disk allowed Maxwell to see and study the direction of the angular momentum vector when a spinning object is subjected to a jolt/impact.

The key to this design is to make the contact point/tip of the top at its own center of mass, then any frictional force in contact with the stem will produce a torque about the contact point at a right angle to the direction of friction that creates the stabilizing force (students of physics may recognize application of the right hand rule here). When this brass bell shaped top is spinning an interesting stability can occur- push on the pointed stem and the top will push back, forcing the stem against that object, and friction will cause the stem to roll along and trace the edge of the object. ![]() It was kind of fun for limited amounts of time and I wanted to know the name of it, but I couldn't find anything about it since I couldn't remember the name of the 'toy' or the company that made it.
