The video begins with a close-up of a person's hand holding a white smartphone. The person then places a clear, round, bubble-like object on the back of the phone. The object appears to be made of a gel-like substance. The person then picks up a glass of water and pours it onto the object, causing it to expand and fill with water. The person then places the phone face down on a white surface next to the glass of water. The person's finger is shown pressing on the phone's screen, and the water-filled object appears to be absorbing the water from the glass.
