Spinning top levitates in mid air.
This was considered impossible until not long ago.
Consists of a strong base magnet with a magnetic spinning top properly weighted to hover above as long as the top keeps spinning at the right rpm. -Spin-stabilized magnetic levitation-
The product is called a Levitron.
Really cool for kids to play with and get interested in science.

LEVITRON - The Amazing Anti-Gravity Top
Introducing The New DELUXE PLATINUM EDITION
The new LEVITRON top - for the new Millennium. This deluxe version of the new SUPER LEVITRON features a high-tech, flying saucer look. The advanced design includes adjustable legs for ease in leveling the device. An instructional CD-ROM is included with each LEVITRON DELUXE PLATINUM EDITION TOP.
The LEVITRON has been called the best new science toy in a generation - by members of the American
Association of Physics Teachers, and it is the perfect gift for the person that has everything.
Spin the top - and watch it float! The Levitron spins and surfs on magnetic waves! Pass your hand above, underneath, and around the top. It will continue to spin and float only touching air! The LEVITRON floats free in space, supported only by the repelling magnetic force produced by permanent magnets no batteries required!. A scientific theorem, that was advanced over a century ago, states that this is impossible - yet this amazing top levitates right before your eyes! You must see it to believe it!
Magnetic levitation
From Wikipedia, the free encyclopedia
Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational acceleration and any other accelerations.
The two primary issues involved in magnetic levitation are lifting forces: providing an upward force sufficient to counteract gravity, and stability: ensuring that the system does not spontaneously slide or flip into a configuration where the lift is neutralized.
Magnetic levitation is used for maglev trains, contactless melting, magnetic bearings and for product display purposes.
Diamagnetically stabilized levitation
Earnshaw's theorem does not apply to diamagnets. These behave in the opposite manner to normal magnets owing to their relative permeability of (i.e. negative magnetic susceptibility). Diamagnetic levitation can be inherently stable.
A permanent magnet can be stably suspended by various configurations of strong permanent magnets and strong diamagnets. When using superconducting magnets, the levitation of a permanent magnet can even be stabilized by the small diamagnetism of water in human fingers
Rotational stabilization - Spin-stabilized magnetic levitation
A magnet or properly assembled array of magnets with a toroidal field can be stably levitated against gravity when gyroscopically stabilized by spinning it in a second toroidal field created by a base ring of magnet(s). However, this only works while the rate of precession is between both upper and lower critical thresholds—the region of stability is quite narrow both spatially and in the required rate of precession.
The first discovery of this phenomenon was by Roy M. Harrigan, a Vermont inventor who patented a levitation device in 1983 based upon it.[12] Several devices using rotational stabilization (such as the popular Levitron branded levitating top toy) have been developed citing this patent. Non-commercial devices have been created for university research laboratories, generally using magnets too powerful for safe public interaction.
