What is a gyroscope?
A gyroscope is a spinning wheel mounted so that it can tilt freely. Once spinning, it resists any change to its axis: balance it on a fingertip, a string or the edge of a stand and it stays upright, apparently defying gravity. The effect is conservation of angular momentum, the same principle that keeps a bicycle upright and steers spacecraft. Desk gyroscopes, spinning tops and precision models all rely on it.

Who is this collection for?
🌀
For a child who asks why the top does not fall
From 8 upwards. A gyroscope balancing on a fingertip or a string is the demonstration of angular momentum that every physics teacher wishes they had.
🎁
For a desk gift that goes beyond the pen
Metal spinning tops, precision gyroscopes and brass models for engineers, scientists and collectors.
⚙️
For anyone who likes precision objects
Machined metal, balanced rotors, satisfying spin times. Objects to handle as much as to display.
How to choose a gyroscope
Pick by what you want to do with it: demonstrate physics, fidget quietly at a desk, or own a machined instrument that spins for minutes.
| Type | Best for | Spin time | Price |
|---|---|---|---|
| Classic gyroscope toy | Physics demonstrations, ages 8+ | 1 to 2 minutes | $25 to $40 |
| Metal spinning tops | Silent desk fidgets, adults | 3 to 8 minutes | $25 to $40 |
| Antigravity and precision gyroscopes | Balance tricks, collectors | 5 to 10 minutes | $35 to $80 |
| Brass and antique style gyroscopes | Display, gifts, instrument lovers | varies | $75 to $280 |
Most gyroscopes start with a pull string or a finger flick; precision models come with a stand and a launcher. None need batteries.
The science in two lines
A spinning mass has angular momentum along its axis, and changing the direction of that axis needs a torque. Gravity pulling on a tilted gyroscope supplies a torque, but instead of falling the axis swings sideways: precession. The faster the spin, the slower and steadier the precession.
Our three bestsellers
Gyroscope: your questions, answered
What is a gyroscope?
A gyroscope is a spinning wheel or disc mounted so its axis can rotate freely in any direction, used to maintain orientation and measure angular velocity thanks to the conservation of angular momentum.
What is a gyroscope used for?
Gyroscopes are used in navigation systems, aircraft and spacecraft stabilization, smartphones for orientation sensing, drones, and as fascinating desk toys that demonstrate angular momentum.
What is the gyroscope in the human body?
The vestibular system in the inner ear acts like a biological gyroscope, helping the body sense rotation, balance and spatial orientation.
What is a gyroscope in mobile phones?
Smartphone gyroscopes are tiny MEMS sensors that detect rotation and orientation changes, enabling features like screen auto-rotate, gaming controls and augmented reality.
