Taps design 10 - What am I supposed to do here :(

Another in a long series of taps. This one is also an 'automatic waving one'. It's obvious the the middle one is for the water and the left one for soap. Or is it? Because there's nothing coming out of it and the soap container is placed there as well! But I'd like to see it work just to play with the sensors. I bet they put both spouts to close to each other and the soap kept coming out while rinsing hands ;). However, I like the simplicity of its design.
