Turn your faucet into a water fountain
When I brush my teeth I usually use my hand to scoop water into my mouth for rinsing. It's not the greatest method but I don't like the wasteful use of little paper cups or the constant washing of regular cups in the bathroom. Isn't there a better solution?
Yes, there is. The Tapi from Dreamfarm is a simple device you attach to any straight faucet. With the Tapi installed, just leave it alone for normal water flow and squeeze the end to send water arcing to your mouth.
The Tapi is made from dishwasher-safe rubber and although it's shown in several colors on the Dreamfarm site, it's currently available only in the steel wool color (shown above). Seems like it would be handy on the kitchen faucet too.
