Now, shower head to tell if you are taking too long in bath

Scientists have developed an illuminated 'smart' shower head that changes from green to red to tell users when it is time to get out, helping them save water.
Scientists from Tufts University have created the Uji illuminated shower head that gradually changes from green to red while in use, reminding users when they are taking too long.
Once the Uji has turned red, it makes users realise how much time is passing.
The current prototype is set to turn fully red after seven minutes, although the duration may be adjustable on a commercial version, according to a report on NPR, formerly National Public Radio.

According to its inventors, a six-month study indicated that the Uji reduces showering time by an average of 12 per cent, which should add up to a savings of approximately USD 85 a year in a home setting.
In a university setting, that figure goes up to USD 200 a year, website 'Gizmag' reported.

"It encourages [people] to take shorter and more energy efficient showers," said one of the co-inventors, Brett Andler.
"By letting people become aware of how long they're in the shower, we've actually been able to cut shower time by 12 per cent," Andler said.
Inventors expect the Uji shower head, priced at about USD 50, to be available for sale early next year.
