Super-scientist Nina and her young Experimenters travel the UK in search of digital wonders. With the help of Nina's five animated sense Neurons, they explain how amazing technlogy is all around us, helping make our everyday lives faster and easier.

Nina investigates how 3-D printers work - with the help of Felix, her touch neuron.

Experimenters Colin and Ethan visit Nina in her lab and discover that 3-D printers print real objects in lots and lots of layers. Next, they have a go at making objects with lots of layers for themselves, just like a 3-D printer. Finally, they go to see 3-D printing in action and find out how the printer knows what to do.
