ALLEGRA BOVERMAN/Staff photo. Gloucester Daily Times. Gloucester: East Gloucester Elementary second grader Kayla Calomo reacts to the remote controlled antics of a "shark blimp," that is being operated by one of her classmates with the help of two Gloucester High School students, David St. Peter and James Cavanaugh, during a daylong visit to the school by Gloucester High School Honors Physics and Physics of Robotics classes students on Friday. The blimp, while not built by students, helps demonstrate buoyancy and explain the mechanical devices it's comprised of.
