A spinning top, or simply a top, is a toy with a squat body and a sharp point at the bottom, designed to be spun on its vertical axis, balancing on the tip due to the gyroscopic effect. Once set in motion, a top will usually wobble for a few seconds, spin upright for a while, then start to wobble again with increasing amplitude as it loses ...
The stem may be used as a handle to pick up the top, and is also used to spin the top into motion. When a tippe top is spun at a high angular velocity, its stem slowly tilts downwards more and more until it suddenly lifts the body of the spinning top off the ground, with the stem now pointing downward. Eventually, as the top's spinning rate ...
In classical mechanics, the rotation of a rigid body such as a spinning top under the influence of gravity is not, in general, an integrable problem.There are however three famous cases that are integrable, the Euler, the Lagrange, and the Kovalevskaya top, which are in fact the only integrable cases when the system is subject to holonomic constraints.

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.
Twenty-sided dreidels are unique as they are not spinning tops but twenty-sided dice instead. [4] While not mandated (a mitzvah) for Hanukkah (the only traditional mitzvot are lighting candles and saying the full hallel), spinning the dreidel is a traditional game played during the holiday. [5]
