Transcript

Hey, it's me, Destin. Welcome back to Smarter Every Day. We are here at Lookout Mountain, Alabama again at orbit shot glass. I made a video years ago called The Mystery of the Prince Rupert's Drop about this peculiar little piece of glass where it's really. Really tough. But if you even nick the tail, it explodes. So what I'd like to do today is I... Read More

Questions & Answers

Q: What makes Prince Rupert's Drops so tough?

Prince Rupert's Drops are made by rapidly cooling molten glass, resulting in high compressive stress on the outside and high tensile stress on the inside. This makes them tough and resistant to external force.

Q: Why do Prince Rupert's Drops explode when the tail is nicked?

When the tail of a Prince Rupert's Drop is nicked, it releases internal tension and creates a fracture wave that propagates through the glass. This sudden release of stress causes the drop to explode.

Q: What did the experiments with epoxy reveal?

The experiments with epoxy aimed to observe the spatial fragment distribution of exploded Prince Rupert's Drops. While the results were not as expected, the footage captured the shockwave and fragmentation patterns, providing valuable insights.

Q: How does the viscosity of the epoxy affect the explosion?

Viscosity plays a role in the explosion of Prince Rupert's Drops. If the epoxy is too rigid, it impedes the explosion, resulting in less movement and fragmentation. On the other hand, if the epoxy is too liquid, it may not produce the desired effect.

Summary & Key Takeaways

• The video revisits the concept of Prince Rupert's Drops and the peculiar properties they possess.

• The host collaborates with experts to create new Prince Rupert's Drops using molten glass and epoxy.

• The video documents various experiments to understand the explosion and spatial fragment distribution of Prince Rupert's Drops.
