If you're that particular breed who rinses after brushing by slurping water from the faucet (you know who you are), then Scott Amron's newest creation might do you some good, and for an affordable $3.00 to boot. We're familiar with his electrical experiments, but this Brush & Rinse innovation keeps it manually real. Running water pours into a hole at the head of the brush or body and spurts from the base of the brush or the end tip, creating a fountain-like stream for effortless rinsing, swishing, swooshing, and sloshing (and hopefully spitting).
You might recognize Scott's design from ID Mag's most recent Annual Design Review, where the product was actually photographed incorrectly, with water flowing in reverse through the wrong hole. Even so, it still appears to work okay, so good for you Mr. Amron--that's foolproof design for ya.
