It's impossible to split Oreo cream filling evenly between both wafers, MIT study finds

"I thought there must be some perfect method of twisting to make this happen, because it works for other fluids," Owens, a PhD candidate in mechanical engineering at MIT, told As It Happens guest host Dave Seglins.

"But what we found out is essentially that Oreo cream is stronger than it is sticky. So when we twist it perfectly, instead of splitting in the middle, it just delaminates from one of the wafers, and so you end up with one wafer with no cream and one wafer with all the cream."

The findings were published in the journal Kitchen Flows, a special issue of the journal Physics of Fluids.
