The video starts with a close-up shot of a clear glass ball on a white surface. A person's hand holding a black pen enters the frame and begins to draw around the ball. The person draws a circle around the ball and then adds shading to create the illusion of light reflecting off the glass ball. The person continues to add details and shading to the drawing, making it look more realistic. The video ends with the person lifting the glass ball, revealing that it was a drawing.
