Fun with chemicals: A worker from Liquid Petroleum stirs a racquetball in a bowl of liquid nitrogen as curious onlookers watch. He asked the kids what they thought the ball would do — bounce or break? Answer, it broke, shattering into pieces on the ground when he dropped it. Behind the onlookers are big rigs, on display for Big Truck Day at Guilderland High School on Saturday.
