Prince Rupert's Drop EXPLODING in Epoxy Resin at 456,522 fps - Smarter Every Day 273

A video on YouTube. In Science & Engineering, a Krater category.

Summary by Krater

Destin Sandlin visits Orbix Hot Glass to recreate Robert Hooke's seventeenth-century experiment suspending a Prince Rupert's drop in epoxy resin. Using high-speed cameras running up to 200,000 frames per second, he explores the fracture wave propagation and fragmentation distribution when the drop's tail is nicked inside the resin block.

What it concludes

Nicking the tail of a Prince Rupert's drop encased in epoxy resin causes the drop to explode rather than shatter instantly.
A shock wave propagates along the axis of the bulb before the main fragmentation wave begins.
Higher viscosity of the surrounding epoxy resin impedes the explosive fragmentation of the encased Prince Rupert's drop.
