In the video, a person is holding a plastic bag filled with water and fish. The person is standing in front of a body of water, and they slowly lower the bag into the water. As the bag is submerged, the fish inside the bag begin to swim out into the water. The person holds the bag for a few moments, allowing the fish to adjust to their new environment. Eventually, the person releases the bag completely, and the fish swim away into the water. The video captures the moment of transition for the fish as they move from the confined space of the bag to the open water.
