Here, a security barrier designed to prevent vehicle bomb and terrorist attacks gets tested against a 15,000 lbs truck (almost 7 tons). Things get… pretty messy!
The truck speeds up to 50mph (80 km/h), hitting the barrier with immense force, about three times higher than what it takes to lift a Boeing 747. The barrier wobbles but doesn’t even budge, while the lorry’s engine block is squashed and the entire truck is basically destroyed.
Dean Alberson, a research engineer at the Texas A&M Transportation Institute said that the barrier is part of a project to protect international U.S. embassy bases; he also said that the safety of the driver is not a priority. The anti-ram vehicle barrier, which is being referred to simply as “bent pipe”, emerged unscathed from the test.

Andrei's background is in geophysics, and he's been fascinated by it ever since he was a child. Feeling that there is a gap between scientists and the general audience, he started ZME Science -- and the results are what you see today.
