Scientists used observations of the angle at which dogs urinate and laboratory tests with jets of fluid to design a urinal that produces far less splatter than usual

Laboratory tests using a jet of water have helped physicists determine the ideal angle of urination to minimise splashback at a urinal, and led to an elongated design for urinals that drastically reduces splatter.
“The idea originated exactly where you think it did. I think most of us have been a little inattentive at our post and looked down to find we were wearing speckled pants,” says Zhao Pan …
