A generous school parent purchased a 3D printer for James Hilburt's math classes at the J. S. Jenks Middle School in the Chestnut Hill neighborhood of Philadelphia and Hilburt is getting the students excited about designing their own projects by printing out 3-d stackable cups, a rubik's cube-like 3d puzzle, a complete chess set and small replicas of the Disney Castle and the Eiffel Tower. To help the students understand design and construction, Hilburt is first having them build a bridge with Popsicle sticks. For the 3d printer projects, Hilburt downloads digital templates onto his computer and loads them into the printer; a rapidly moving arm lays down layer after layer of threadlike strands of melted plastic through a small nozzle head to build the creations from the ground up, taking nearly a day for the more complicated ones.

At a polling place on election day in Chestnut Hill, Philadelphia, voting machine technician Tony Pirrone explains how static electricity can short the voting machine and shut it down when the machine inspector touches the officer control button on the back to enable the voter to vote. After seeing one machine shut down and have to be reset several times, voters at the poll waited in line for the one good machine, not trusting that the finicky one would register their votes. Pirrone assured all who would listen that even though the machine needed to be reset repeatedly, all votes had been accurately recorded and stored on the machine cartridge which would be transported by a police officer to a central location for the official tally.
