You've probably seen the viral picture of a drippy faucet night light that was, unfortunately, one-of-a-kind. But you can make your own, and this project from Instructables member boston09 doesn't even require an electrical outlet, because it's a battery-operated LED! The glowing "drip" is made from a pacifier nipple. All the steps are at Instructables. Link -via Boing Boing
