Getting complex machines to perform simple tasks was the object of the Rube Goldberg Machines display April 21 at Zachary High School.
Seniors partnered up to design complex machines that ranged from the artistic to the zany, true to Rube Goldberg form.
Goldberg, a Pulitzer Prize-winning cartoonist, was best known for his wacky invention cartoons. His illustrations featured complex devices performing simple tasks in some of the most indirect ways and inspired others to create similar machines.
A marble lowered by a pulley onto a ramp that rolls into a display of dominoes, which tip over a cup of water into a plant is one of many examples of chain reactions found in Rube Goldberg machines.
Zachary High students were graded April 21 by science teachers, who judged the machines on several criteria, including the use of six simple machines: inclined plane, wedge, lever, wheel and axle, screw and pulley. The students’ machines also were given marks on creativity and completion of task.
Examples of machines included the watering of a household plant, providing a duck hunter with a better aim, cutting a slice of cake and turning on a light bulb.
