There is no general term for this device but from your description it is something sometimes described as a roller ball clock. the roller balls are in effect ball bearings. the device can only be used indoors, in a static location for obvious reasons. By the way there was some sort of mechanical gravity feed device used to drop the cyanide pellets ( called) Eggs for executions in films dealing with the gas chamber such as (I want to live) This was shown in all of its tortuous mechanical detail as to exactly how the chamber and execution protocols worked.
Balls that are not hollow include solid rubber balls, such as those used in certain sports like racquetball or handball. Other examples are solid metal balls, like those used in bearings or as weights, and solid plastic balls used in various applications. Additionally, some types of exercise balls, like medicine balls, are filled with dense materials rather than being hollow.
This sounds like hematite which may have a metallic luster.
Bakugan look like little balls that pop up when you put them on metal. Some bakugan look triangular shaped.
Straightening a bent metal coat hanger is difficult because the metal has undergone plastic deformation, meaning it has permanently changed shape and lost its original structure. The forces applied during bending cause the metal's crystalline structure to rearrange, resulting in internal stresses. Additionally, the thin and flexible nature of a coat hanger makes it challenging to apply sufficient force uniformly without risking further bending or breaking.
A metal compound is held together by the attraction of the positive nuclei in each atom and the mobile electrons from the outer energy level of each atom. The fact that the electrons are free to move around the structure means that even if the structure changes shape there will still be an attraction between them and the positive nucleus of the atoms.

Metals break when subjected to a force or stress that exceeds their strength. This can lead to the breaking of atomic bonds within the metal structure, resulting in fracture. Factors such as impurities in the metal, its crystal structure, and temperature can also affect its breaking point.
it is the atoms metal.
Copper is a non-ferrous metal whose tensile strength can be increased by hammering or rolling. This process, known as cold working or cold forging, helps align the grain structure of the metal, resulting in improved strength and hardness.
If you are trying to hit the jack on the green, you are playing petanque, which involves throwing or rolling metal balls as close as possible to the target jack. The objective is to score points by having your balls closer to the jack than your opponent's balls.
Rub my metal balls or rubber balls.
Cobalt's fracture refers to a type of fracture that occurs in metallic cobalt. It is characterized by a clean break in the metal with no deformation or twisting. This type of fracture is common in metals that are hard and brittle.
In metalworking, rolling is a metal forming process in which metal stock is passed through a pair of rolls. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is termed as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is termed as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process and cold rolling processes the most tonnage out of all cold working processes

They sound like metal rolling over metal.
