Some new research finally answers a pressing scientific question- why does some poo float and some poo sink? 

An accidental discovery on the microbiomes in mice revealed that the buoyancy of poo is linked to the microbiota present in the intestines. The research done on the mice confirmed that the microbiota in the gut plays a role in how poo turns out.

UOA Research Fellow Dr Joel Rindelaub says that a higher rate of 'floaters' coming out of an individual may be indicative of poor intestinal health.
