Air date: Oct 06, 2013

Join our expert contributors Phil Torres, Lindsay Moran and Kyle Hill as they explore new technology, including a new kind of high-density plastic that can be inserted into students' backpacks or teachers' white boards in hopes of deflecting gunfire. Plus, Kyle visits an Indiana dairy farm that is turning cow manure into clean natural gas (CNG) to fuel their fleet of trucks.
