Physicists probe
urination ‘splashback’
problem
US physicists have studied the fluid dynamics of urine “splashback” - and found tips to help men and women with their accuracy and hygiene.
Using high-speed cameras, the team filmed jets of liquid striking toilet walls and studied the resulting spray.
Splashback was low when the jets were used close up with a narrow “angle of attack”, said the Brigham Young University team.
They will presenttheir researchat anAmerican Physical Society meeting.
“In response to harsh and repeated criticisms from our mothers and several failed relationships with women, we present the splash dynamics of a simulated human male urine stream,” reads their conference abstract.
Reduction techniques:
- Getting as close as possible - a smooth unbroken stream is better than droplets
- Angling the stream - aiming sideways or downwards instead of straight at the toilet water/wall
- Placing toilet tissue in the bowl to soften impact
- Hydrophobic coatings for toilets
- Being a “sitzpinkler” - sitting down instead of standing
