The most readily observable case of the Magnus effect is when a spinning sphere (or cylinder) curves away from the arc it would follow if it were not spinning. It is often used by football and volleyball players, baseball pitchers, and cricket bowlers. Consequently, the phenomenon is important in the study of the physics of many ball sports.
Behind the finished vase are the spinning tools used to shape the metal. Metal spinning, also known as spin forming or spinning or metal turning most commonly, is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part. [1] Spinning can be performed by hand or by a CNC lathe.
LCS-1 is a hollow sphere 1.12 m (3 ft 8 in) in diameter with a wall thickness of 3.2 mm (0.13 in). [3] The sphere was constructed from two hemispheres, made by spinning sheet metal over a mold. These hemispheres were fastened to an internal, circumferential hoop by 440 countersunk screws, then milled and polished.
Fig. 1.—Arago's spinning disk Fig. 2.—Babagge and Herschel's experiment Fig. 3.—Slit disks used by Babbage and Herschel. Arago's rotations is an observable magnetic phenomenon that involves the interactions between a magnetized needle and a moving metal disk.
Mach took some issue with the argument, pointing out that the rotating sphere experiment could never be done in an empty universe, where possibly Newton's laws do not apply, so the experiment really only shows what happens when the spheres rotate in our universe, and therefore, for example, may indicate only rotation relative to the entire mass ...
Most Baoding balls consist of a pair of hollow spheres, each containing a chime that rings when an inner ball strikes the outer sphere. Many modern examples are decorated with cloisonné and brass wire; these are essentially decorative since they easily chip when dropped or rubbed together. Baoding balls can also be made of solid jade, agate ...

Sphere Within Sphere (Sfera con sfera) describes a series of spherical bronze sculptures by Italian sculptor Arnaldo Pomodoro. In 1966, Pomodoro was commissioned to create a 3.5-meter sphere for Expo 67 in Montreal.
