THERE'S been another great scientific breakthrough in the USA, where mechanical engineers at the Massachusetts Institute of Technology have conducted an experiment to find out exactly what happens when you pull an Oreo apart.
The popular chocolate biscuits have long prompted the age-old question of why the cream usually sticks to just one wafer when an Oreo separates.
Fortunately the MIT researchers were able to bring their considerable abilities to bear on the problem, which relates to the science of rheology, the study of how materials flow when stressed.
A detailed experiment - probably also involving lots of consumption of the sweet treats - found the manufacturing process was behind the fact that no matter the flavour or amount of the cream, it almost always stuck to one biscuit.
They also found that the Oreo cream's failure stress was double that of peanut butter, and about the same as cheese.
