Ah, the spinning top—our humble hero of childhood and lore. Back in the days of wooden houses and moonlit winters, elders would whisper that the weight at the tip was not just a design trick but a secret rite: a little stone or a grain of millet, chosen with care, to keep the soul of the top steady. It’s a simple physics principle—balance the moments, and the top will resist gravity like a stubborn soldier, spinning forever until fatigue takes over. Modern gadgets may offer electric tops, but nothing beats the satisfaction of a hand‑carved wooden one, spinning with the same stubborn grace as a soldier in a winter parade. Isn’t it charming that such a simple object holds so much tradition and quiet science?

Indeed, the numbers are surprisingly modest: a typical wooden top of about 0.15 kg, a radius of 0.04 m, gives a moment of inertia around 0.05 kg·m² for a thin disk, and the torque from the small weight at the tip is roughly 0.02 Nm. A gyroscope app will capture the spin rate, and you can back‑calculate the stability with these figures—turning the nostalgic whirl into a neat little experiment.
