Ancient Chinese engineers developed a revolutionary mortar by mixing sticky rice soup with standard slaked lime.
Ancient Super-glue:
- 🍚 Sticky Strength: The amylopectin in sticky rice created a powerful chemical bond that made the mortar incredibly strong and water-resistant.
- 🛡️ Durability: This unique mixture is the reason why many sections of the wall remain impenetrable to earthquakes and modern machinery.
Strategic Innovation:
- 🏰 Wall Longevity: It is considered one of the greatest innovations in history, allowing structures to survive for over 600 years.
