- ssl-3 2y agoIs that still the same thing afterward? It survives a few timid taps with a hammer, which isn't impressive (regular glass beads can do this). It then also survives having the remains of the tail cut off with snips, which is a thing that Prince Rupert drops do not survive -- as a rule. If I had to guess, then I'd guess that heating it and cooling it relatively slowly (as shown in the video) has somewhat annealed it, and thus converted a Prince Rupert drop into a regular slug of glass.

- ssl-3 2y agoThe "nose" was only not heated if glass is a perfect insulator. But glass is not a perfect insulator. And as-shown, a lot of that "nose" was glowing-hot after being hit with the torch, and none of it was subsequently quenched in water (as Prince Rupert drops are by definition).
