Deft defecators done in 12 seconds
Fluid dynamics explain how amount and viscosity of faecal mucus makes it easy to poo
From a 4kg cat to a 4000kg elephant, any animal takes only around 12 seconds to ‘do their business’. This is what a team of US scientists found after thoroughly studying the process of defecation in over 40 animal species. They then developed a theoretical fluid dynamics model that shows how viscosity changes in faecal mucus ease excretion.
