Fountain (juggling)

The fountain is a juggling pattern that is often used for juggling an even number of objects. In a fountain, each hand juggles separately, and the objects are not thrown between the hands. For example, in a four-ball fountain, each hands juggles two balls independently.

A fountain can be synchronous or asynchronous. In a synchronous fountain, both hands throw at the same time, while in an asynchronous fountain, the hands alternate throws.

The fountain is used for juggling even numbers of objects because other patterns which alternate between hands (such as the cascade) do not work well for even numbers.
