The morning walk in the shower belongs to many people's daily ritual. However, most do not worry about water consumption. After all, about 18 liters per minute rush through a conventional shower. The Bavarian tinker Hartmut Wolf has now developed a shower head, with which the water consumption can be reduced by two-thirds. This is made possible by the fact that no drops of water flow from the shower, but air bubbles filled with air. A so-called vortex chamber generates a fast rotating vortex in the shower head that draws in air. Water and air then mix to form a foam that bubbles out of the holes in the shower head. Wolf assures that the water pressure is strong enough to also rinse out long hair shampoo. In addition, no lime can fix itself in the shower head, as its holes would automatically blow free when used regularly.
