What makes adults and children linger and become addicted to playing at the Science & Technology physical store? It's the perfect solution when your mind is in a knot or your heart is unsoothed!

Have you ever seen a spinning top that can do somersaults?

Spinning a top is a childhood fun for many people; you just need to flick a small string and the top will keep spinning!

Have you ever seen a spinning top that can stand upright without being swung by a string?

This upside-down spinning top, which looks like a small mushroom, will magically stand up with its round mushroom head when you spin it with your finger!

Because the inverted top is missing a part (the upper half), its center of gravity is slightly lower than the center of the sphere. When the inverted top spins,

Because the contact point between the sphere and the ground is not located on the axis of rotation, it will cause the contact point to slide, thus generating friction and creating the torque required to make the gyroscope stand upside down.

The metal inverted spinning top has another fascinating little secret: if you place it on a smooth surface and spin it, the friction will produce a sound like a sword being drawn from its sheath!
