Mystery of Prince Rupert’s Drop at 130,000 fps

Another interesting video by Destin at SmarterEveryDay demonstrating the mystery of the Prince Rupert’s Drop. Watch it here.

What’s cool is that the glass droplet actually explodes from damaging the tail — i.e. hitting the head with the hammer isn’t what breaks it — and so the high tension left over from it’s formation releases, starting a chain reaction at ~1 mile/second. Awesome!



do you ever feel like you’re just sort of 


like all your friends go out and do things and have fun and do stupid things with their best friends and instead of doing all that you’re just sort of this mildly entertaining thing that people take an interest in once in a while but they wouldn’t really care if it was gone

like you just sort of exist but you don’t really mean anything
