Twisted, licked, dipped! Who likes to eat Oreos? But you know what, a study revealed that the activity of 'playing' Oreo is actually quite impossible, aka impossible!
The research is published in the journal Physics of Fluids and was led by Crystal Owen, a fluid dynamics student at the Massachusetts Institute of Technology.
The research was carried out by testing the printable properties of nanotubes exactly like measuring Oreo spins. The researchers started with an instrument called a rheometer, a pair of plates that can sandwich liquids together, and rotate them to measure the strength of the liquid.
In the case of Oreos, the researchers wanted to see what would happen to the inner 'creme' if they rotated the outer 'wafer'. The key measurement is the 'yield pressure' or the amount of force required to separate the wafer from the crme.
The study authors also tested these biscuits with a homemade 'Oreometer'. It's a clamping device that uses a rubber band and a coin to separate the wafers, developed by co-author Max Fan, a scholar at MIT.
Owens says he and his colleagues hope to split the Oreo filling down the middle under some experimental conditions. But the result was not so. No matter how fast they spin the wafer, the cream always sticks to one side.
"Turns out there's no trick to it... It's kind of disappointing that there's no secret touch," said Owen. In the end, the faster the scientists turned the wafers, the harder it was to split the cream on both sides. This was quoted from Pop Science, Tuesday (26/4/2022).
