The Marion Natural History Museum welcomed a visit from Mark Whelan, engineer with Sippican/Lockheed Martin Corp. Mark allowed us to experiment with compression, stability and buoyancy. We built our own submarines and figured out how to make it sink, but not too fast. Then we held a race to see whose submarine sank the slowest. The group had a great time working with all the materials and we’d like to thank Mark and Sippican/Lockheed Martin for the wonderful program.
