Here are some great facts and videos showing one amazing pooper, the penguin.
Below is a figure showing the pressure at which a penguin can poo. Beyond all discoveries, this must be known by the world.
The basic principle is penguins do not want to poop where they nest. Thus a longer projectile the better.
But let’s dig deeper. The pressures penguin poo generates when launching liquid is around 10 kPa (77 mm Hg). When a more “olive oil” type substance is expelled it’s pressurized around 60 kPa (450 mm Hg).
