Free: Splash

Innovations in hygiene infrastructure, such as , use contoured surfaces and specific "critical angles" to eliminate splashback. By applying fluid physics to these designs, facilities can reduce the spread of unhygienic fluids, save on cleaning resources, and improve overall public sanitation. Efficient Swimming

: Splashing represents energy diverted into the air rather than into forward propulsion. Splash Free

: Research indicates that air pressure is a primary driver of splashing; in a vacuum, droplets often do not splash at all. Innovations in hygiene infrastructure, such as , use
