Outdoor: Behind the Explorium building, choose between one of four outdoor STEM activities to participate in and enjoy! Guests will move inside the Explorium for food and cake. No private play allowed inside the Museum. In the event of inclement weather, the party will be moved indoors or rescheduled.
