1. A mechanical toy comprising:
- an elongated, transparent tubular sidewall having a longitudinal axis and a circular cross-section;
- a pair of circular inserts, each said insert mounted adjacent an end portion of said tubular sidewall and cooperating with said sidewall to define an enclosed tube;

- a ball-receiving chamber in said enclosed tube, said chamber defined by said tubular sidewall, a circular insert, and a top surface of said granular material when said tube is in a vertical position;
- a sphere in said enclosed tube, said sphere having a diameter in excess of 50 percent of the diameter of said tubular sidewall circular cross-section and a mass sufficient to displace a quantity of said fine granular material when subjected to a periodic upward thrust.
