In the video, a person is seen holding a green water balloon maker over a pool. The person then pulls the handle of the maker, causing water to fill the balloons. The balloons are then released into the pool, creating a splash. The person repeats this process several times, filling the pool with water balloons. The balloons are green and appear to be made of a thin, flexible material. The pool is surrounded by a gray inflatable barrier, and the water is clear and blue. The person's actions are deliberate and controlled, indicating that they are experienced with using the water balloon maker.
