“Wizzing” to the top of the Red Folder this week is a group of physicists at the “Splash Lab” at Brigham Young University who have studied the physics of “splashback” that occurs when people urinate. Using high-speed cameras the researchers filmed jets of liquid from a “synthetic urethra” striking toilet walls. They found that the stream of liquid breaks up into droplets when it is about 15 cm from the urethra exit. “Wizz kids” Tadd Truscott and Randy Hurd suggest that apart from sitting down on the toilet (and risk being called Sitzpinklers by their German friends), men should get nice and close when doing their business to eliminate splashback. Take a look at their video about “Urinal dynamics” above.
