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 Bethan, Corey and Rhianna visit Nina in her workshop and see what happens when you build a dam in a stream. Next, they go to a real beaver dam to find out why beavers build them and how they use the pool behind it. Finally, they have a go at building a dam themselves and discover why beavers are such brilliant builders. Show less
