In the video, a man is seen standing in front of a table with several large water bottles. He is wearing a green shirt and has a watch on his wrist. The man is holding a clear plastic bag and appears to be demonstrating how to use it to fill a water bottle. He carefully places the bag over the mouth of a water bottle and then uses a straw to suck air out of the bag, creating a vacuum. As he does this, the water in the bottle begins to rise, filling the bag. The man continues to suck air out of the bag until the water reaches the top of the bottle. He then removes the bag and the straw, and the water bottle is now full. The man looks satisfied with his demonstration and smiles at the camera.
