(TODAY Show) - A group of Princeton University physicists have concluded that an Oreo cookie will always split with the cream on the same side.
"Here’s how it works,"
. "Position the Oreo box so that the text on the packaging is facing the right way, and take out the cookie in the upper left hand corner. If the cream ends up on the left biscuit on one cookie, it’ll end up on the left biscuit for every cookie in that box. If it’s on the right, vice versa."
It means you can actually guess with 100 percent accuracy which side the cream will fall on.
Researchers bought hundreds of Oreos and performed many tests, including one that tested to see what would happen when the cookies were twisted, rather than lifted, apart.
They found it all had to do with the cookies' manufacturing process.
"As each cookie is being assembled, the hot filling is poured onto one wafer before the second is added on top,"
. "That gives the bottom cookie more of a chance to adhere to the creamy filling, allowing it to stick to that side when ripped apart."
