Chicago Children's

From Chicago Sun-Times:

On February 21, over 100 area high school students participated in a Rube Goldberg competition designed to test their engineering skills, sponsored by Argonne National Laboratory and Chicago Children’s Museum. Toy dolls, falling golf balls, and rising balloons were all part of colorful contraptions that aimed to zip a zipper in at least 20 steps. The first place winners, from Revis High School, will advance to the national competition in Wisconsin in April.
