The video shows a close-up of a clear plastic bag with water being poured into it. The water is flowing in a steady stream, causing the bag to bulge and move. The bag appears to be lying on a surface, and the water is being poured from above, out of frame. The water is clear and appears to be at a high temperature, as it is causing the bag to expand rapidly. The video is shot in a well-lit area, and the sound of the water hitting the bag can be heard.
