In the video, a person is seen holding a yellow gear with a white center in their hand. The gear has several holes around its circumference. The person then places the gear on a table and presses down on it with their hand, causing it to depress slightly. After a moment, the person removes their hand, and the gear springs back up to its original position. The gear appears to be made of plastic and is designed to be flexible. The person repeats this action several times, each time with the same result.
