Splash-free urinals? Scientists investigate new 'splash avoidance' technique

When a drop of liquid hits a surface at a sufficiently high speed, it splashes—that much isn't in doubt. But sometimes splashing isn't helpful. Researchers are working on methods of 'splash avoidance' that could prevent splashback of harmful or unhygienic fluids in a range of settings, from hospitals to kitchens - and perhaps even urinals.
