It’s the great equalizer. Even the world’s richest monarchs–with their gold-gilded sinks and ivory toothbrushes tipped with the coarse tail fur of DNA-recombinated duck-billed platypuses–face the same problem every day. We all brush our teeth, and with a frothy mouth full of mint or bubblegum, debate whether to leave a fluoride-laden rabies bite on the nearest cup, or simply crane our neck under the sink faucet. But a new invention will change everything.

The Rinser Toothbrush, by Scott Amron, channels faucet water through its body, spraying it into the air like a fountain, where it can be sipped and swished with ease.
