"Invisible" here means: Weapons that can't be detected with a metal detector, used in airports and government buildings. How dangerous are non metal weapons, really? This video wants to find out.
Airport security is still much more tight than before 9-11. But is it tight enough? Mohammed Atta and his fellow terrorists used box cutters to hijack the planes. Those can't be brought aboard airplanes anymore, the detectors are (hopefully) too sensitive. But there are still many weapons that
a) are small enough to fit in a pocket without too much bulging b) won't be seen by a metal detector
Jörg Sprave tests four non metal knifes (flint, wood, plastic, and ceramics) against a block of ballistic gelatin, "Mythbusters" style. Then, a carbon fibre slingshot is used to fire pebbles into the gelatin.
The end result is clear: More security is needed. All of the tested weapons can seriously harm, even kill, a human beeing. Therefore suitable body scanners and mandatory frisking is a must.
As a bonus, steel and lead balls are also shot at the gelatin, and a samurai sword finishes it off.
