The Doomsday Scam. For decades, aspiring bomb makers — including ISIS — have desperately tried to get their hands on a lethal substance called red mercury. [more inside]
Smarter Every Day examines the physics of Prince Rupert's drop. Deceptively simple to create, these teardrop-shaped glass structures demonstrate the physics of tempered glass in spectacular fashion. Previously
From Sheffield, England to Yongbyon, North Korea, nuclear plant cooling towers are coming down! And pretty much without a hitch. Things didn't go quite so well, though, for an old flour factory in Turkey, which just rolled over onto its roof. D'oh!
Prince Rupert’s Drops are quickly cooled teardrop shaped glass pieces that have amazing physical properties. While tough on the big end, they will explosively shatter if broken on the small end.
Terrorism is always disgusting, but this is just plain gross. Wired wonders if terrorists will start carrying explosives inside their bodies. They don't explain whether they'll, uh, "remove" them before detonation. Will Argenbright start issuing rubber gloves? And on a more serious note, does this underscore the fact that planes can never be fully secure, meaning I can get my plastic lunch knife back? (I think so.)
