The physics of Oreo splitting - mklabgr - 07-29-2026 The physics of Oreo splitting Summary This article highlights two quirky physics studies exploring how structural mechanics affect the way we experience popular treats. First, MIT researchers developed a 3D-printed "oreometer" to measure the torque required to split an Oreo cookie, discovering that a slow twist yields the cleanest break and that the cream almost always sticks to just one wafer due to manufacturing patterns rather than how it is twisted.  Second, researchers in the Netherlands engineered 3D-printed chocolate "metamaterials"—materials with precise internal geometric designs—and found that controlling how the chocolate shatters when bitten directly enhances its mouthfeel, with test subjects rating chocolates that crumble into more pieces as tastier.
