Crescenta Valley team works on their mechanism First Place Honors
For the third year, La Canada High School took first place by accurately directing 17 tennis balls into a trash can. The 500-pound mechanism, "A Momentary Lapse of Reason," was made of 20 metals arms held in place by springs. The balls were placed in cups that, when released, catapulted the balls through the air and into the metal can.
