A MAELSTROM is a more powerful version of a whirlpool, with a stronger current and more chaotic movement. A JACUZZI is a type of hot tub that uses jets of air and water to create a whirlpool effect. A SPA is a place where people can relax and enjoy treatments such as massages and saunas. An EDDY is a smaller version of a whirlpool, usually created when a current meets an obstacle. A VORTEX is a powerful whirlpool that is created when a large amount of water is forced through a narrow opening.
