Artist Rafael Lozano-Hemmer created an installation that lets the public water the lawn at Spanish tower Torre de Madariaga using a water hose that is equipped with a built-in heart rate sensor.

Pulse Drip consists of a custom-made spray head with a small sensor that detects the heart beat when the user puts his or her finger on it. The water hose has an automated electromechanical valve that controls the flow of the water and matches it with the user’s heart beat.

Users can take the hose wherever they want and it will water the lawn to the beat of their hearts.

The Pulse Drip includes a rechargeable battery, a radio transmitter, and an Arduino processor.
