Tired of that same old monotonous water? Bored with water that doesn't look like futuristic alien mouthwash? Need to make your midnite bathroom appointments more exhilarating? Then you need to get the blue LED faucet attachment from ThinkGeek. You can turn any faucet in your home into a streaming blue lagoon of techie-bliss in just minutes. How does it work? Just attach to the end of your faucet (universal adapters included), and when the water flows through the magic chamber, it simply turns on the blue LED array and illuminates the stream with a soothingly powerful crystal blue hue.
