If you’ve never heard of a Prince Ruperts Drop before, let’s discuss those real quickly before you watch this clip. They are glass beads which have been hardened by dipping molten hot glass into cold water. This creates a glass structure that looks not too dissimilar from a sperm. On the tail end of the Prince Ruperts Drop it is fragile and can break off easily. But on the droplet end, these glass beads are practically indestructible when hit head on.
This clip from the SmarterEveryDay YouTube channel is actually a follow up to a previous video where they shot the Prince Ruperts Drop with bullets. Viewers pointed out that they weren’t using the best possible rounds for the experiment. So, they’re back again and this time they are using a .38 special and firing rounds at the indestructible Prince Ruperts Drop droplets of glass.
As you can see, these Prince Ruperts Drops defy logic. They are stronger than any glass formation you ever come in contact with:
Interestingly, the Wiki entry for Prince Ruperts Drops makes the claim that structures similar to these exist in nature when lava from volcanoes falls into the water. That seems like a pretty badass artifact to get your hands on if you’re a collector of odds and ends.
