A whirlpool is a swirling mass of water, often caused by the meeting of opposing currents. It is usually found in bodies of water such as rivers, oceans, or lakes. It can be dangerous for swimmers or boats as it can pull them under and spin them around. You can also find whirlpools in washing machines or bathtubs which agitate the water to clean clothes or provide a massage respectively.
