[asrvtxuw] Wisconsin bubbler

Create (as a joke) a pair of drinking fountains, one labeled for Wisconsin people and one for others.  The Wisconsin one makes bubbling sounds when the button is pressed but does not emit water.  Or, emits soap bubbles.

Alternatively, a water cooler with multiple tabs: pushing the Wisconsin one merely bubbles air through the water in the jug and again does not emit water (this will require some engineering, because the incoming air then needs to be taken back out.).

If you want water, use the water fountain, not the bubbler.
