A group of physicists from the USA explained the phenomenon of Oreo cookies, when almost all the cream remains on only one of the halves when separated.

The reason for the gap is in particular the Oreo conveyor production: the cream is applied to one cracker, and then covered with the second, thus creating a difference in adhesion between the two halves of the cookie.

As a result, you just need to see which side of the cookie was oriented in the pack and you can determine with 80% probability which of the halves will have the cream when twisting.
