In the video, a person is using a hair dryer to blow air onto a ball of aluminum foil. The foil ball is being held in place by the person's hand. As the air is blown onto the foil ball, it begins to expand and take on a more spherical shape. The foil ball appears to be quite large and is being held in place by the person's hand. The hair dryer is being used to blow air onto the foil ball from different angles, causing it to expand and change shape. The person's hand is steady, and they seem to be controlling the expansion of the foil ball with the air from the hair dryer. The background is not visible, and the focus is on the foil ball and the hair dryer.
