Stand Aside, Alexa And Siri: You Control This Stereo With Water

That's the idea behind Pour Reception, an art project by Tore Knudsen, Simone Okholm Hansen, and Victor Permild, featured recently on Creative Applications. It's a radio that you tune by filling, drinking, and tapping on two glasses of water. By pouring water from one glass to the other, you scrub through frequencies to find a new station. By touching a jar, you can fine-tune its signal and remove distortion. Finally, to turn the music down, you just plunge your finger right into the water.
