“What do you think will happen?” a worker from Air Products, right, asks an attentive gathering as he holds, with tongs, a racquetball over a bowl of liquid nitrogen.

Little kid, big truck: On Saturday morning, a bright yellow cement mixer beckons a curious kid during Big Truck Day, held at Guilderland High School to help raise funds for the Class of 2016. A racecar, fire apparatus, dump truck, armored patrol car, emergency vehicles, and a school bus were also on display.
