Applications

The Quark top can be enjoyed in several ways:

Gadget
Just spin it and be mesmerized by its nearly perpetual motion. Or watch closely for the interesting moves it makes as it slows. Spin it upside down, and watch for some interesting motions - different spin angles create different results.

Business
Create a timer to limit the duration of meetings. Make decisions based on its stopping angle.

Games
Compete for longest spin time. Compete for fastest time to precision balance. Compete for best guess of duration after the top starts to wobble. Compete for most time within drawn circle while holding the spin surface by hand. Draw a path on the spin surface and try to follow the path by tilting the surface.

Educators
Demonstrate numerous laws of physics (momentum, aerodynamic drag, friction, gyroscopic precision, center of gravity), engineering (pseudo stable systems, materials, dynamic balancing, laser scanning, engineering optimization), math (deceleration curve, harmonics (between precession rate and spin rate), calculus, differential equations) and more. An entire course in physics, engineering, or math can be centered around the Quark top.

Quark - Quiz

Take the Quark top true-false quiz!

Low center of gravity is essential to long spins.
The top  stabilizes due to the coriolis effect.
Initially, the Quark top is slowed primarily by tip friction.

Answers

Here are the answers:

Surprisingly this is not a significant factor.

No, coriolis is an apparent force that as a result of the earth's rotation deflects moving objects (as projectiles or air currents) to the right in the northern hemisphere and to the left in the southern hemisphere.

No, initially aerodynamic drag is greatest.
