How To Predict Cream Side When You Twist Apart An Oreo

Finally, scientists have used their knowledge and perseverance to quell the most pressing of questions: When the cookies of an Oreo are pulled apart, on which side will the cream remain?

It turns out that the fate of the cream is not random, so your old and faithful tactic for deciding bets is now tragically obsolete. The white filling, Princeton physicists discovered, will end up on the same side every time.

After going through dozens of boxes of Oreos, subjugating the cookies to lab experiments involving heavy-duty load frames and rotation rigs, the curious group found a simpler explanation for the cream question, Quartz reports.

Position the Oreo box so the label is facing the right way, take out the cookie in the upper left corner and pull it apart, they instruct. If the cream ends up on the left cookie, it will end up on the left cookie for every Oreo in the box. The same goes for the right cookie. 

After making that discovery, “it was easy to make the leap that it’s a feature of the manufacturing process,” scientist Dan Quinn told Quartz.

While we may never know Nabisco's top-secret Oreo-making process, an episode of Discovery Channel's "How It's Made" went behind the scenes of similar Newman-O cookies.

To manufacture the Oreo lookalikes, a machine lays cream filling onto a bottom wafer, and another machine places the second cookie on top. Since the cream is warm when it lands on the first cookie, it fills each crevice of the wafer, sticking to it like hot glue. Once the second cookie comes into play, the cream has cooled down.

After that, the cookies are placed in the same direction in each box, so the cream will end up on the same side no matter how you twist it.

Since you've gained this knowledge, you can no longer fairly break a tie using the classic Oreo trick. But who said anything about fairness?
