Why Honeycombs are Tilted at Exactly 13 Degrees (It’s Not Why You Think!)

For centuries, beekeepers thought bees tilted their cells to stop honey from dripping out. They were 100% wrong. Discover the 13-degree secret that turns a simple honeycomb into an engineering marvel. In this video, we debunk the oldest myth in beekeeping and explore the structural mechanics of beeswax. We look at groundbreaking 2021 research and a fascinating 1985 NASA space experiment to understand how bees sense gravity to build their hives. It turns out, the 13° tilt isn't about hydrodynamics—it's about surviving the crushing weight of 25kg of honey. References Guo, T., Li, M., Heng, L., and Jiang, L.
