In the video, a person is seen wearing a white lab coat and a blue shirt underneath. They are holding a clear plastic water bottle with a white cap. On top of the bottle, there is a yellow stick that is balanced horizontally. The person then blows on the stick, causing it to bend and then return to its original position. The person repeats this action several times, each time with the stick returning to its original position. The background is not visible in the video.
