Named after the "top quark" sub-atomic particle, the patent pending Quark top is now available at the company web site and will soon be available in toy and gift stores, mail order catalogs, and through premium-incentive distributors.

According to inventor Jim Lewis of Micro Logic, the exceptionally long spin times are the result of precision-machined parts, a carefully engineered combination of weight distribution, balancing technology, tip topology, material selection, handle optimization, and exacting proportions. Most of the Quark top’s mass is located in the dense flywheel with everything towards the center from the flywheel manufactured as light as possible. The top can be spun on an included 8" mirror, chosen for its low friction.

Balance plays a critical role in the Quark top's long spin times. Six inverted counterweight pockets allow for adjustment of weight distribution to bring the center of gravity directly over the center of the tip. An included laser assists in determining proper balance in a process where counterweights are moved in a specific pattern.

The Quark top tip is made of high strength carbon steel. The handle is optimized by providing enough diameter to allow powerful spins yet it is small enough to generate several revolutions during launch. Finally the simple contour of the disk reduces surface area and aerodynamic drag.

In addition to the normal use of a spinning top as a toy and high-tech conversation piece, the Quark top can be used as a timer for business meetings, a decision-maker, and to play one of several games described in its instructions. Educators can demonstrate numerous laws of physics, engineering, math, calculus, differential equations and more with the Quark Top.

The Quark top is priced at $49.95 in brass, $149.95 in tungsten and $2,495 in solid 14K gold. Custom imprinted logos are available. A dreidel version is also available.

The Quark top can be purchased online at www.miclog.com or by calling 201-962-7510 or by mailing to Micro Logic, 31 Industrial Ave., Mahwah, NJ 07430. Domestic and international shipping is available. Dealer inquires are welcome.
