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 Alexander, Billie and Marianna visit Nina in her workshop and discover what a cantilever is and what happens when you put weight on a long cantilever. Next, they go to the Forth Bridge and find out how long cantilevers stay up. Finally, they have a go at being a bridge themselves, to explain how they hold up heavy weights, like trains. Show less
