Abstract:
An angular momentum spinner includes two or more rotating arms loaded with an adjustable sliding block for each arm and laid symmetrically about a rotating center. Each sliding block is controlled to move along the corresponding rotating arm. Such a spinner can display the conservation of angular momentum vividly and intuitively, and can also serve as an amusing toy for children. The spinner can be used as teaching equipment for various students to demonstrate the theorem of angular momentum conveniently, intuitively and amusingly.

Claim (Index 1):
An angular momentum spinner comprising:\n a pedestal; a base ball bearing disposed on the pedestal, the base ball bearing having an inner ring fixedly mounted to the pedestal and an outer ring configured to rotate relative to the inner ring; a lifter spring which passes through the base ball bearing, wherein the lifter spring has a first end and a second end and is connected at the first end to a center region of the pedestal; a lifter ball bearing disposed concentrically above the base ball bearing, the lifter ball bearing having an inner ring connected to the second end of the lifter spring and an outer ring configured to rotate relative to the inner ring of the lifter ball bearing; and two or more arm assemblies joined to the outer ring of the base ball bearing, each arm assembly comprising:\n a rotating arm joined to the outer ring of the base ball bearing and extending in a radial direction; \n a sliding block disposed on and radially slidable along the rotating arm; \n a grooved support member having a groove on its outer surface, the grooved support member being mounted on the rotating arm and disposed adjacent to the outer ring of the lifter ball bearing; and \n a connecting wire connecting the sliding block to the outer ring of the lifter ball bearing, the connecting wire being disposed in the groove of the grooved support member, wherein the connecting wire is configured to pull the sliding block along the rotating arm as the lifter ball bearing is pressed downward by compressing the lifter spring; \n wherein the two or more arm assemblies are distributed evenly in an angular direction around the base ball bearing.
