We've found the toothbrush of the future. Yes, it's electric, but not in the way you're used to. Most toothbrushes are pretty good at getting toothpaste onto your teeth; now, the Rinser Brush also helps wash it off.

A groove below the head of the toothbrush lets water from the tap flow through a plastic grate set in the handle. One push of a button, and a small motor propels the water up in a smooth laminar-flow plume straight to your mouth. It's an instant drinking fountain, built into a toothbrush.

For the traveler, it means not having to slurp water from the faucet or lapping it up from cupped hands. At home, it means not needing disposable cups or a glass that needs to be washed. For parents, it's one more way to convince kids that hygiene is fun. You can preorder one now for $35.
