General Admission Discounts and Promotions

ASTC Reciprocal Admission

Participating members of the ASTC reciprocal network receive general admission to COSI*. Benefits do not apply to ASTC members whose place of residence is less than 90 miles from COSI. Per ASTC policy, the distance is measured “as the crow flies,” meaning that it is based on the linear radius, not driving distance. Science centers within 90 miles of one another are excluded from the program unless lifted by separate agreement. COSI will admit up to 2 adults and 4 children on an ASTC reciprocal membership.
* ASTC free reciprocal admission to COSI does not include special add-on experiences or exhibitions. Tickets for these experiences may be purchased at COSI’s Box Office.
**ASTC & ACM reciprocal admission cannot be used together or combined with any other special offers, promotions or discounts.
