In the video, a man is seen underwater in a swimming pool. He is wearing a large plastic container on his head, which is secured with green ropes. The container appears to be a makeshift breathing apparatus, allowing the man to stay underwater for an extended period. The man is shirtless, and the water is clear, with tiles visible on the pool floor. The man seems to be demonstrating the use of the plastic container as a breathing apparatus, possibly for scuba diving or other underwater activities.
