This is unique glass, which can spin on the table.

At first glance, the rotation of the glass seems unbelievable and difficult to understand.

But in fact this “phenomenon” is as simple as the rotation of a wheel. You just take a glass (empty or with a drink inside), put it on the table and with a slight movement of the hand give the glass a spin… and something amazing happens: the glass rotates on the table right in front of your eyes.
