Sure, the fall is all about the centre of mass and how it moves when the pizza is lifted. If you treat the slice as a thin plate, its moment of inertia is higher about the long axis, so when you tilt it the torque from gravity pulls it sideways. The probability of landing edge‑up versus top‑up depends on the speed of the drop and the pizza’s shape. In practice, a perfectly round pizza will land on its edge about one third of the time if you drop it from a finger’s height, but the real world adds slip, crust texture and human error. So yeah, there’s a neat pattern—just a little chaos in the numbers.
