The STEAM Expo is a fun, engaging, educational area featuring free hands on activities in science, technology, engineering, arts and math.

Fair Saint Louis is proud to partner with xplor planning and organizing all of the activities in the Purina Festival Zone. xplor curates and creates inspiring experiences for businesses, individuals, and families.  Part experiential marketing company, part event planners, part consensus builders, and part connectors, xplor is the first company of its kind in the St. Louis area.  We vet, concept, and bring to life events that impact bottom lines and result in real relationships.

The STEAM Expo will be located in the teardrop on the north side of the Arch in the Purina Festival Zone just past gate 3.
