Maybe You Should Talk to the Guy at the X-Ray Machine...

Before you try to take something like this through the airport secuity:

An Oregon college student's science project forced the evacuation and shutdown of a terminal at Eppley Airfield in Omaha on Wednesday.

The student had been participating in a science fair at Creighton University in Omaha, FBI spokeswoman Sandra Breault said.

"The device had a legitimate purpose and was harmless but had a suspicious appearance, which triggered an appropriate response by TSA and law enforcement," Breault said.

Breault said the student is working on a doctorate, but did not release the student's name or other details — such as the type of science project that prompted the scare.

The airport's north terminal was evacuated and shut down for about two hours Wednesday after X-ray screening workers spotted the science project in a carry-on bag, the federal Transportation Security Agency said.

The terminal was reopened around 2 p.m. Wednesday.

"Out of an abundance of caution, screening operations were suspended and the terminal was evacuated," a TSA written release said. "The Omaha Police Department's Explosive Ordnance Disposal Unit cleared the item with negative findings."
