Frequently Asked Questions - Gyroscope Thames & Kosmos

How do I spin the gyroscope?

Hold the gyroscope by the outer frame, then pull the string quickly through the slot on the rotor. Alternatively, you can spin it manually by twisting the rotor with your fingers.

What is the purpose of the gyroscope?

The gyroscope demonstrates principles of angular momentum and gyroscopic precession. It helps understand how rotating objects maintain orientation and resist changes.

Why does the gyroscope not fall over when spinning?

When the rotor spins rapidly, it creates angular momentum that makes the gyroscope resistant to changes in its axis. This is why it stays upright or precesses slowly instead of falling.

Can I replace the string if it breaks?

Yes, the string can be replaced with any thin, strong cord or shoelace. Ensure it is long enough to wrap around the rotor a few times.

Is the gyroscope suitable for young children?

No, it is recommended for ages 8 and up due to small parts that could be a choking hazard. Adult supervision is advised for younger users.

How do I clean the gyroscope?

Use a soft, dry cloth to wipe the gyroscope. Avoid using water or cleaning liquids, as they may damage the internal components.

What can I do if the gyroscope wobbles?

First, check that the rotor is spinning freely and the axle is not bent. Ensure the base is level. If wobbling persists, it may indicate a manufacturing defect – contact Thames & Kosmos customer service.

Why does the gyroscope spin in a circle on its stand?

This is called precession. When a torque is applied (e.g., gravity pulling down), the gyroscope rotates perpendicular to the applied force, causing it to spin around in a circle instead of falling.

Can I use the gyroscope outdoors?

Yes, but avoid dusty or wet surfaces. Dust can affect the rotor's spin, and moisture may cause rust on the metal axle. Use on a clean, flat surface.

Where can I get a replacement gyroscope or parts?

Thames & Kosmos does not sell individual spare parts. If the gyroscope is defective, check the warranty or contact their support for assistance. You may also find replacement toys from authorized retailers.

INTRODUCTION

From smartphones, tablets, and video game controllers to airplanes and

telescopes, gyroscopes are found in many places. With this kit, you can explore the astonishing powers of the gyroscope

and learn some of the physics principles behind its behavior.

The word "gyroscope" comes from the Greek words gyro, for "circle" or "rotation," and skopein, meaning "to see." The name was originally coined by a scientist who built the device in an experiment to see Earth's rotation. Essentially, a gyroscope is a spinning wheel mounted inside one or two gimbals.

WHAT'S HAPPENING?

Why do gyroscopes behave the way they do? A gyroscope demonstrates gyroscopic motion, which is the tendency of a spinning object to maintain the orientation of its rotation. Rotating objects have angular momentum, and this momentum must be conserved. Any change in the orientation — or angle — of movement is a change in the angular momentum, and the object will resist this change.

Bicycles and motorcycles take advantage of gyroscopic forces. An upright bike that is moving forward has two spinning wheels that naturally resist tipping over.

Gyroscopes work extremely well zero-gravity environments like outer space. The movement of the International Space Station is controlled by four huge gyroscopes on its four corners. Your gyroscope has a weighted rotor in the center. Its large mass gives it greater angular momentum, which allows it to spin for longer.

EXPERIMENT 1

Balancing on the stand

Place the half sphere on the table.

Thread the string through the hole

in the axle and wind it up tightly around

the axle. Start the gyroscope spinning by

putting quickly and smoothly on the string. Quickly plazs the twin-lip spin the stand. How

quickly place the axle tip onto the stand. Ho long can you get the gyroscope to balance?

EXPERIMENT 2

Gyroscope In the sphere

Wind the string around the axle as you

did in experiment 1. Place the gyroscope

in the sphere with its axle tips resting in

the cradles. Guide the string out slightly through the sweep. Hold the corners in one

through the hatch. Hold the sphere in one hand and pull the string swiftly with the

other hand. Roll the sphere around. What

do you notice about its behavior?

EXPERIMENT 3

Balancing on your finger

Start the gyroscope spinning using the string. Carefully place the axle tip of the spinning gyroscope onto your fingertip. How long can you balance the gyroscope? What other objects can you balance it on? A pen? A ruler?

EXPERIMENT 4

Balancing on a string

You will need a helper for this. Start the gyroscope spinning using the string. Then holds the string very light between two hands approximately 6 to 12 inches apart. Place the notched axle tip of the gyroscope on the string. For how long can you balance the gyroscope?

EXPERIMENT 5

Spinning box

Start the gyroscope spinning inside the sphere as you did in experiment 2. Quickly place the sphere back into its original box, with the axle pointed diagonally from one corner to another corner. Close the box. Place the box onto its corner. What do you notice? Can you get the box to balance on its corner?
