The Fluid Dynamics of Minimizing "Splashback"

Wow, fluid dynamicists sometimes study some really fun problems, like the fluid dynamics of urinating and trying to minimize "splashback". As some physicists have discovered using their patented "Water Angle Navigation Guide" (note the acronym), one of the keys to reducing splashback is to use a narrow angle of attack. (Note: Do not confuse this with "backside attack" from organic chemistry.)

The physics of urination seems to have become a popular research topic lately. It looks like competition for an Ig Nobel prize is going to be pretty stiff.

(Tip of the cap to whoever posts for Physics Today on Facebook, and thanks to Martin Gould for pointing out the acronym above. I actually missed that when I first read the article.)
