MOSH will open its doors free of charge on Saturday September 23, as part of Smithsonian magazine’s thirteenth annual Museum Day Live!, an initiative in which participating museums across the United States emulate the spirit of the Smithsonian Institution’s Washington DC-based facilities, which offer free admission every day, and open their doors for free to those who download a Museum Day Live! ticket.

The Museum Day Live! ticket is available for download at Smithsonian.com/museumday.

Visitors who present the Museum Day Live! ticket will gain free entrance for two at participating venues on September 23, 2017. One ticket per email address is permitted. For more information about Museum Day Live! 2017 and a full list of participating museums and cultural institutions, please visit Smithsonian.com/museumday.
