In the video, a person is holding a small red water pump in their hand. The pump is being held over a clear plastic cup filled with water. The person then places the pump on the counter and pushes down on the handle, causing water to pump out of the spout and into the cup. The person repeats this action several times, each time pumping more water into the cup. The video focuses on the action of pumping water and the relationship between the pump and the cup.
