Apparatus and methods relating to pop-up fountains for spas where the fountain includes a fountain head that has a first set of orifices and a second set of orifices, and at least two operating states. The first orifice set is active, and the second orifice set is inactive, when the fountain head is in a first operating state. The second orifice set is active when the fountain head is in a second operating state. The fountain head transitions between the first operating state and the second operating state in response to a change in position and/or a change in fountain head pressure.
