A study showing that nearly all mammals take the same amount of time to urinate has been awarded one of the 2015 Ig Nobel prizes at Harvard University.

These spoof Nobels for "improbable research" are in their 25th year.

The team behind the urination research, from Georgia Tech, won the physics Ig.

Using high-speed video analysis, they modelled the fluid dynamics involved in urination and discovered that all mammals weighing more than 3kg empty their bladders over about 21 seconds.

Their subjects included rats, goats, cows and elephants - and although the findings reveal a remarkably consistent "scaling law" in bigger beasts, they also emphasise that small animals do things quite differently.

Rats can urinate in a fraction of a second, for example. This might make rodents a poor choice for studying urinary health problems.

An amazing conclusion! Wunderbar! I never even got the idea to time rodent hydrological evacuation.

It would probably make a fascinating thesis for someone's PhD.

Yes! It is precisely the kind of research that we need desperately. The conclusion could certainly alter our destiny. But I am sure that all of our top research centers are already actively engaged in the solution to this and other pressing problems like it that humanity faces in the 21st century.

At the very least, it has encouraged me to time my own toilet uses.

Do not forget to write it all down.

That is valuable data that the research team could use!
