Super scientist Nina and her young Experimenters travel the UK and Europe in search of amazing structures. With the help of Nina's five animated sense Neurons, they explain how and why construction works and what makes buildings and structures so brilliant.

Experimenters Aaron and Sylvia visit Nina in her workshop and discover what makes windmills' sails turn in the wind. They go to an old windmill in Amsterdam to find out what happens inside while the sails are turning outside. Finally, they do an experiment that explains how the cogs inside a windmill work and help us do lots of different jobs. Show less
