"One of my big problems with so-called green products is that they make your life worse. It makes life a little less fun to have a shower head that restricts water, or a light bulb that doesn't give enough light to read. You've got create a product that makes you aware, but not in a negative way" (Paul Priestman in [1]).

Designed by Paul Priestman, the Waterpebble monitors water going down the plug hole when you shower.  Memorising your first shower and using it as a benchmark, Waterpebble then indicates, via a series of ‘traffic lights’, which are universally recognised and intuitive,  flashing gently from green through to red, when to finish showering:

Each time you shower Waterpebble automatically fractionally reduces your shower time helping you to save water without needing to think about it [2]; "over  a period it trains you to have shorter showers" (Paul Priestman in [1]).

Waterpebble is designed for recycling and to be broken apart; the plastics and electronics can then be separated and recycled. To open the Waterpebble the consumer simply needs to acess the small key indent on the perimeter of the pebble.
