Free Play, MoMath's free general admission hours (in person)

Free Play is an event at the National Museum of Mathematics (MoMath) during which general admission to the Museum is completely free, with extended Museum hours. It is hosted by MoMath and invites visitors who have not yet been to the Museum — and their friends — to explore it at no cost. Free admission is first-come, first-served, and all attendees, including children, must be registered; early arrival is strongly encouraged, as entry is limited once capacity is reached.
