Visitors of all ages are invited to discover solutions to science and engineering challenges at Science Saturday. Learn about buoyancy, density, and how boats stay afloat! Build your own boat and test how much cargo it can hold! This is a drop-in activity, so feel free to join the fun at any time from noon to 4 p.m. Activities are included in regular admission and free for Hagley members. Use Hagley’s main entrance off Route 141 in Wilmington, Delaware.
