The rotating Table

Just about everything here is rotating, both the disks and the table. Start a disk rotating, and try to control how it moves when the base is also rotating.

The rotating table influences the motion of the round disks and rings across the surface of the table. The centre of the table rotates more slowly than the outer edge. When a disk is placed somewhere on the table, it rotates at the same speed that the table has at that particular place. When the disk subsequently moves across the table, it keeps the same speed. This means that the disk will deviate from the direction of motion of the table as it approaches the edge of the table. A similar effect can be seen for clouds and other weather systems, which deviate from straight paths as they move between the poles and the equator. Another experiment on this theme is the Coriolis Fountain, on the second floor.
