## About

Taking place at the Saint Louis Science Center Makerspace gallery on the second floor, this weekend drop-in maker challenge invites children and parents to collaborate on creative engineering builds. Participants test wind-tunnel aeronautics with custom-folded flyers, assemble beginner LED circuits with guidance from museum educators, and explore structural bridge engineering using recycled geometric shapes. Stroller parking is provided right outside the Makerspace entrance. Elevators connect directly from the Oakland parking lot and main lobby. Accessible family restrooms and companion care rooms with changing facilities are located steps away near the McDonnell Planetarium skywalk.
