Prosecutor: Students' 'bomb' was tin filled with salad dressing and cinnamon

New Jersey authorities say a group of 10- and 11-year-olds upset about bullying devised an immature and unrealistic plot to bomb a high school with vegetable oil, salad dressing and cinnamon.

Passaic County Prosecutor Carmen Valdes said Friday that the children filled an empty mint tin with the ingredients. Officials say the device was not flammable or dangerous, and none of the kids had a match or a lighter.

Prosecutors say children weren't arrested or charged. They will be required to enter an agreement with the Clifton police department that includes mandatory counseling.

They could face charges if they don't follow requirements of the agreement.
