Question

what is prince rupert's drop? can you explain how hard it is and how can we break it? Explain the experiment and also answer who discovered it?​

Answer 1

Answer:

The outer layer of glass shrinks as it cools and forms a solid shape. When the glass core of the drop eventually cools, the molecules inside have no where to shrink to because the outer layer is already set, so they pull toward each other, creating a super high tension inside the bulb, which eventually hardens.
