MIT Study Overturns Belief About Eggshell Strength

Research reveals eggs are tougher when dropped on their side, challenging long-held assumptions and offering insights for packaging and design.

Overview

  • A peer-reviewed study from MIT demonstrates that eggs are less likely to crack when dropped horizontally rather than vertically.
  • Controlled experiments involving 180 drop tests and 60 compression tests showed horizontally dropped eggs absorb more energy before breaking.
  • The findings challenge the widespread belief that eggs are strongest when dropped vertically, a misconception rooted in confusion between stiffness and toughness.
  • Researchers suggest these insights could inform improved egg packaging designs and inspire bio-inspired engineering applications.
  • Published on May 8, 2025, in Communications Physics, the study highlights the importance of empirical testing in overturning entrenched scientific assumptions.
