Why the Prince Rupert's Drop is UNSMASHABLE ๐ง๐ฅ
Main summary
Key takeaways
Summary
- A Prince Rupertโs drop is formed by dripping molten glass into cold water.
- The outer layer cools and solidifies quickly, while the hotter interior cools and contracts more gradually. This creates strong compression in the exterior and substantial tension inside.
- The compressed bulb can withstand impacts such as a hammer strike, but the thin tail is fragile. Breaking the tail releases the internal stresses, causing a shockwave that shatters the drop at supersonic speed.
