20 Weirdest Things Found By Airport Security (Slideshow)

The crews who work for airport security come in contact with thousands of people on a daily basis. Most of those people are carrying totally mundane things in their carry-ons. However, the security team occasionally crosses paths with people trying to smuggle unapproved items through x-ray machines and inspections.

Some of these items are innocuous, some are dangerous, and some are even alive. All are prohibited on board. Clearly, some passengers don't know what they can bring through airport security. Passengers have tried to get away with bringing fireworks, human skulls, and even weapons concealed in food on board.
