Are you or someone in your family taking long wasteful showers? The solution is this cool new Water Pebble. Just place this innovative little device down by the drain and as you shower it monitors the water usage and changes colors like a stoplight to let you know when time's up. To make it easier on you, it first benchmarks how long your average shower is and then incrementally shortens its stop time each time you shower by seven seconds. In just a couple of weeks, you'll be properly trained, taking quicker showers and significantly reducing your water usage without even thinking about it. Smart and simple idea.
