Cardboard Boats

Classmates cheer as Todd Signs, 12, right, and Mark Frazzini, 13, paddle their cardboard boat across the swimming pool at Kirtland Middle School on Tuesday, May 22, 2007, in Kirtland, N.M, during the seventh-grade Advanced Science class boat race. The students were allowed only duct tape, cardboard and plastic wrap to build a boat that would carry them across the pool two times. Signs and Frazzini nearly sank before reaching the finish.
