Tim Cook, the CEO of Apple, has joined forces with Eric Schmidt, the executive chairman of Google, to invest in a Silicon Valley startup which makes fancy shower heads.

The New York Times reports that Nebia has designed a new kind of shower head that it says can reduce the amount of water used by up to 70 percent. Average showers take around 20 gallons of water, but Nebia says that showers using its shower heads only use about 6 gallons.

The shower head reduces the amount of water used through nozzles that break water down into droplets. That means that more water comes into contact with your body.
