NORTHFIELD - A Northfield Elementary student teamed up with an Air Force colonel for a science project which set out to determine how strong you have to be to tear a phone book.

Col. Derek Routt, of the New Jersey Air National Guard, worked with fourth-grader Mason White to figure it out.

They took first place in the school’s content and White got an A.

The colonel worked with White as part of the guard’s community outreach programs.
