L’Oréal Water Saver
Besides laundry-washing and lawn-sprinkling, the daily washing of hair uses up a lot of water. L’Oréal's new Water Saver system is designed to help, by reportedly reducing the amount of water used in hair-washing by up to 80 percent. In a nutshell, this involves angling two contained water streams diagonally downward toward one another, so that the droplets from the two streams collide at a central meeting point. As a result, the colliding droplets are blasted apart into much smaller droplets – about one tenth the original size – which proceed out of the system's nozzle at a high velocity.
