The video shows a person's hand holding a large piece of black rock. The rock is irregularly shaped and has a rough texture. The person is holding the rock over a body of water, and the rock is wet, indicating that it has been in the water. The person then submerges the rock into the water, causing ripples and splashes. After a few seconds, the person lifts the rock out of the water, allowing the water to drip off the rock. The person then turns the rock over in their hand, showing its different sides. The rock appears to be heavy, as the person's hand is struggling to hold it. The water is murky, and the surrounding environment is not clearly visible.
