Swirl tap was designed by art student Simin Qiu at the Royal College of Art . He is currently testing a prototype tap and hopes it will go on sale next year . Two spinning turbines in the tap head send the water into a hollow vortex . This uses around 15 per cent less water than traditional taps , the designer claims . The hollow jet is also more gentle to use on the hands than traditional taps .
