Whether you want family members to spend less time in the shower for ecological reasons, for the sake of basic parsimony or just because of the absurd time they spend in there, this is for you.

Waterpebble monitors the water swishing down the plughole, giving you an amber light when you’re halfway through your allotted time, red when it’s time to turn off. It cleverly measures how long you spend on your first shower, then reduces it by seven seconds each time until you’re down to an efficient, but not extravagant, six minutes.
