COSI has reopened after its annual maintenance closure with several new shows for visitors.

A new exhibit, How People Make Things, is based on factory tours shown on Mister Rogers' Neighborhood. The touring show, which includes hands-on activities, was created by the Children's Museum of Pittsburgh, Fred Rogers' company (Family Communications Inc.) and the University of Pittsburgh Center for Learning in Out-of-School Environments.

How People Make Things, which runs through Jan. 8, includes activities such as cutting wax with hand tools, deforming a wire, learning how vacuum forming is used to make ice cream cups, assembling a golf cart and trolley, trying out injection molding and learning how crayons, baseball gloves and carousels are made.

Families also can check out three new planetarium shows: Secrets of the Sun, Starry Night Live and Cell! Cell! Cell!. The popular Jr. Star Safari continues.

Fall hours are 10 a.m. to 5 p.m. Wednesday through Sunday.
