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 5):
The angular momentum spinner of  claim 1 , wherein in each arm assembly, the rotating arm includes a base plate and a roof plate connected together forming a frame structure extending in the radial direction, wherein the sliding block is disposed between the base plate and the roof plate and includes two ball bearing rollers connected by a connector, each ball bearing roller being configured to roll against the base plate or the roof plate, wherein one of the base plate and the roof plate has two ridges parallel to the radial direction and extending toward the other one of the base plate and the roof plate, the two ridges configured to restrain sideways movement of the two ball bearing rollers.
