    en.wikipedia.org/wiki/Crookes_radiometer

    The Crookes radiometer (also known as a light mill) consists of an airtight glass bulb containing a partial vacuum, with a set of vanes which are mounted on a spindle inside. The vanes rotate when exposed to light, with faster rotation for more intense light, providing a quantitative measurement of electromagnetic radiation intensity.

    en.wikipedia.org/wiki/Foucault_pendulum

    Foucault-like precession is observed in a virtual system wherein a massless particle is constrained to remain on a rotating plane that is inclined with respect to the axis of rotation. [ 16 ] Spin of a relativistic particle moving in a circular orbit precesses similar to the swing plane of Foucault pendulum.

  6. Levitron - Wikipedia

    en.wikipedia.org/wiki/Levitron

    The levitated top's stabilizing rotation undergoes natural, gradual slowing, so that the levitation phenomenon fails within four minutes unless external power is supplied to sustain rotation. To levitate the top, a plastic plate is placed on top of the magnetic base, and the top is spun on the plate at 25–50 rotations per second (1500–3000 ...

    en.wikipedia.org/wiki/Globe_of_Peace

    The Globe of Peace (Italian: Mappamondo della Pace) is a large globe located in Apecchio, Pesaro, Italy. It was the Guinness Book of World Records record holder for the world's largest rotating globe until 1999, when it was succeeded by Eartha. It was built over a period of six years by Orfeo Bartolucci, with the stated goal of diffusing a ...
