This one might be my favorite.
It's the U.S. State Department is developing a steel barrier that can immediately stop a speeding 15,000-pound truck.
Yes, this was done intentionally.
This is what happens when a dump truck going 50 mph hits a military-grade concrete barrier. But really, I would love to know the science behind a barrier like that. It's amazing that it can withstand such force, so if anyone can enlighten me it'd be much appreciated.
