MIT Tackles the Best Way to Eat an Oreo Cookie

I heard my niece is entering the research phase of her PhD course, and had to make jokes about the poor grad students who spend all day counting people in public bathrooms or sifting tons of dirt looking for bone fragments just to be listed as et al in the final publication. However, Crystal Owens of MIT's mechanical engineering department got approval for a study of the physics of an Oreo cookie.

Owens aimed to discover if there is any way to twist open an Oreo and achieve creme sticking to both wafers. You are shaking your head no. At least now it's been scientifically proven. Owens and her team used a rheometer, a device that twists cookies open, to test different twisting speeds and different cookie flavors. This involved gluing the cookies to the rheometer's discs, which takes some of the magic out of the experiment. They tested more than 1,000 cookies, both by machine and with hand techniques. The results showed that 80% of the time, the cookies ended up with all the creme on one wafer, no matter how slowly the cookie was twisted or what method was used.

The researchers suggested that Oreo might turn the wafers over so that the printed side could grab the creme. That's not going to happen, because that's branding. It is evident that the creme is more cohesive than adhesive. If you want to eat an Oreo and have a consistent ratio of creme-to-wafer, you can always bite them like you would another kind of cookie. -via reddit
