A San Diego school vice-principal saw an 11-year-old's home science project (a motion detector made out of an empty Gatorade bottle and some electronics), decided it was a bomb, wet himself, put the school on lockdown, had the bomb-squad come out to
destroy X-ray the student's invention and search his parents' home, and then magnanimously decided not to discipline the kid (though he did recommend that the child and his parents get counselling to help them overcome their anti-social science behavior).
When police and the Metro Arson Strike Team responded, they also found electrical components in the student's backpack, Luque said. After talking to the student, it was decided about 1 p.m. to evacuate the school as a precaution while the item was examined. Students were escorted to a nearby playing field, and parents were called and told they could come pick up their children.
A MAST robot took pictures of the device and X-rays were evaluated. About 3 p.m., the device was determined to be harmless, Luque said…
The student will not be prosecuted, but authorities were recommending that he and his parents get counseling, the spokesman said. The student violated school policies, but there was no criminal intent, Luque said.
