Experimenters Livingstone and Oisín visit Nina in her workshop and discover how their shape helps lighthouses stay up in the wind. Next, they visit a lighthouse and work out why the stairs are built in a special way, so people can get to the top. Finally, they do an experiment that explains why lighthouses are built so high up.
