The Hidden Tap by Jalmer Moorman is a new idea that uses a sensor to follow your hands and dispense water. As you move your hands from left to right under the faucet, water goes from hot to cold just like a regular tap. This “faucet” is an interesting technology that who knows in future maybe it will replace the actual faucets. To see how this new idea works check the video below, I’m sure you’ll want one after you’ll see the video. – Via
