A Brush and Rinse brush, however, allows one to easily redirect the flow of water so that it's shooting up in an arc, much like a water fountain. Rinsing is as simple as bending forward and slurping, without the need to waste/wash cups or sully our hands. Sounds like an awesome idea to me, and at $3 I'm on board. It looks like only prototypes are available at the moment, so if you have a spare $1,750 lying around, you can own one of the 27 originals.
