2-li fountain

 air over water

It's a cap that fits 2 liter plastic bottles (pop bottles etc). Fed through it is a short gooseneck with a fine spray nozzle and a pickup tube about as long as a bottle.. and in parallel, a schraeder valve that vents just inside the cap.

To use: fill halfway with water, apply cap. Pump up. Spray. Wash up hands or dishes or water whatever else in sparing quantities.

The shut-off valve could be a setting of an adjustable nozzle to simplify the plumbing.

[edit] formerly 'hobo's fountain'

       maybe we should have a homeless/hobo category for ideas ... the pump-action container of course being incredibly well baked.   

       Now if you can figure a way to get B.Fuller's "Dymaxion Shower Head" to work...

       Yes - garden sprayers and other air-over-liquid dispensers exist. But this device has no container and no pump-action. Those functions are delegated to more-readily-available local materials, to slim the device down to a minimum.   

       Speaking of a minimum.. there is a point where a fine mist does little cleaning. But theres a few orders of magnitude between that flow and the result of pouring straight from a 2-li

       It's a pump sprayer minus the tank, using a found 2L sodapop bottle to hold the liquid.
