Included with COSI General Admission or Membership

Bulldozers, dump trucks, and forklifts converge in downtown Columbus again this year for COSI’s annual Science of Big Machines. Get behind the wheel and operate equipment that builds roads and buildings!

COSI invites you to explore the science and technology of construction by trying it out first hand in a variety of activities and learning with real engineers.

From small tools to big equipment, you’ll discover how big jobs get done. More than a dozen enormous pieces of construction equipment will be on hand to explore.
