The Wizzzer or Wiz-z-zer is a gyrostat toy introduced by Mattel Toymakers in 1969, and introduced the spinning top to modern children. The "twist" (innovation) was the use of a super-spinning, high-tech bearing, that allowed the top to spin at very high speed and remain standing for a long period of time.
The tilting results in a shift of the axle ends along the groove. The direction and speed of the shift can be found from the formula for the precession of a gyroscope: the applied torque is equal to the cross product of the angular velocity of precession and the angular momentum of the spinning mass. The rate of rotation of the internal ball ...
The hemispherical resonator gyroscope (HRG), also called a wine-glass gyroscope [52] or mushroom gyro, makes use of a thin solid-state hemispherical shell, anchored by a thick stem. This shell is driven to a flexural resonance by electrostatic forces generated by electrodes which are deposited directly onto separate fused-quartz structures that ...

The yo-yo is an example of a skill toy. A skill toy is an object or theatrical prop used for dexterity play or an object manipulation performance. A skill toy can be any static or inanimate object with which a person dances, manipulates, spins, tosses, or simply plays.
Box for a WHEE-LO toy The Schylling "magnetic gyro toy" has a design that is very similar to the original WHEE-LO toy. WHEE-LO is a trademark for a handheld toy that propels a plastic wheel along both sides of a metal track with magnets built into the wheel. As the track is tilted up and down, the wheel rolls the length of the track, top and ...
Ludwig Obry's gyroscopic mechanism for steering a Whitehead torpedo, called the "Obry Gear" by the US Navy. Ludwig Obry was an Austrian engineer [1] and naval officer of the Austrian Navy [2] who invented a gyroscopic device for steering a torpedo in 1895.
Foucault published two papers in 1852, one focused on astronomy with the weight free to move on all three axes (On a new experimental demonstration of the motion of the Earth, based on the fixity of the plane of rotation) [8] and the other on mechanics with the weight free to move on only two axes (On the orientation phenomena of rotating bodies driven by a fixed axis on the Earth's surface.
