Peter Mazzone, a lawyer in private life, used what looks like a catapult to show youngsters how a six-year-old could lift a grown man such as himself by means of leverage. Marc Dreier, another adult volunteer, tossed visitors toy balloons that had crumpled after being frozen in liquid nitrogen as the volume of air inside was reduced, but puffed back up to a round shape once the collapsed balloons were handled by the youngsters and adults. Justin Shin, a student at Ridgewood High School, turned his four years of personal study of origami -- Japanese-style paper folding -- into demonstrations of Gina Stonitsch, daughter Mina and Brendan Reilly Left: Justin Shin. Right: Marc Dreier. how simple cards, including playing cards, could be formed into an endless array of shapes. Phread Ayers, a science teacher in the Wayne school system, demonstrated the electronics and physics behind old-style tape recorders of the pre-computer era. Gus Kelty, a Ridgewood High School junior, demonstrated a coil gun, also called a Gauss gun, which uses electromagnetic power to project iron finishing nails into a plastic sheet with a pop and a flash. Kelty noted that the nails sometimes flip in flight because they have not been stabilized, and this flipping reduced their force. The nails bounced off the blue roofing tarp Kelty put up instead of sticking into it. Brendan Reilly, a graduate student at Montclair State University, has voyaged to Antarctica and shared his knowledge of sedimentation as seen in Antarctica at an exhibit set up in the hall, where those exhibits that did not require free motion were displayed. Side rooms were used for televised video viewing. Police, firefighters, emergency corps members, and medical professionals joined the student and teacher volunteers and community members in offering students of elementary and middle school ages an exciting introduction into the wonders of science.
