10 MTY Prince Rupert’s Drop Introduction -

What is Prince Rupert's Drop?

A Prince Rupert’s drop occurs when you have some molten glass melting off of a tool of any kind into a container filled with cold water. Once it cools down, you're left with a piece of glass that is sorta shaped like a water droplet, hence the name. It is methodically peculiar because the front end of Prince Rupert’s drop is industructictable when hit with a hammer but yet, it can shatter with a single puncture to its tail.

What makes a Rupert's drop so strong under compression?

To understand the layers within Prince Rupert’s drop, you need some idea of what these layers comprise. Molten glass is bigger the more heat within because of the thermal expansion coefficient that assures us that heat decides how big the glass will become, solid glass is stronger, stertier glass, and cooling glass for when alternating between both other states. The cooling glass shrinks and pulls in on itself. Think of it as a handful of microminiature parts of glass within trying to unite with the other kinds of glass around itself. The outside of the drops form acers when it solidifies in the cold water when it changes into cooling glass as soon as the first layer is dropped. The drop becomes extremely high because it is circular in form, so while the outside is solid the inside cools down while compressing to make it much stronger because of the tension build up. Once it hardens in a full solid as soon as it's completely cooled down, it becomes a Prince Rupert’s drop.

What causes Rupert's drop to shatter?

The Prince Rupert’s drop shatters when a link on the tail is cut, the storend up testion is unleashed, it travels down the line feeding of its own energy. The difference between a chemically induced reaction and Prince Rupert’s drop reaction is that it isn't chemical potential energy. Prince Rupert’s drop has instead mechanical strain energy.

How fast does Rupert's drop shatter?

The V failure front is the measured velocity of how fast it shattered.
