Place a top on the floor and let go. If it is still, it topples over at once. But give it a fast spin — and it stands up tall, dancing on one tiny point!
Today you'll discover the secret hiding inside every spin. Tap Next to begin! 👉
Imagine two tops sitting on the floor. One is not moving. The other is spinning very fast.
Which one will fall over straight away?
There's a hidden force at work. Let's find out what it is…
Drag the slider to spin the top. Watch how a fast spin keeps it standing straight, while a slow spin lets it wobble and lean.
Push it all the way up to make the top stand perfectly straight!
When the top spins, every part of it is moving fast in a circle. Moving things like to keep going the same way — this is called momentum.
All that spinning makes the top "want" to keep its tilt the same. So when gravity tries to tip it over, the spin fights back and holds it up. Scientists call this gyroscopic stability — a big name for a clever trick!
A spinning bicycle wheel, a frisbee, and even our spinning Earth use this same trick. 🌍
Tap each spinning thing to reveal how it uses the same balance trick as a top.
Tapped 0 of 3 — try them all!
No spin lasts forever. Two sneaky things steal the top's spin:
👉 Tap the words that slow the top down over time. Find both!
As the spin fades, the balance trick weakens — and gravity finally wins. The top wobbles, then topples. 💫
Here's what your scientist brain now knows:
Next time you spin a top, you'll know its amazing secret. Well done, scientist! 🥳
