Life without boats and ships would certainly be different. Experiment with the power of water and recreate the history of how boats were made. Learn about flotation, buoyancy, stability and speed. Navigate a working submarine. Construct a raft, sailboat, and a gliding hovercraft. Race boats to find out which hull design achieves the most speed. Without navigation through the oceans, the great voyages of discovery could hardly have taken place – Columbus, Magellan and the rest. The history of the world might have been quite different.
