Nina investigates how hands work, with the help of Felix, her touch neuron. Experimenters Esther, Lily and Ruby visit Nina in her lab and discover that people can move and bend their hands in lots of different and useful ways. They learn how people can do lots of things that animals can't, like eating with a knife and fork, because they have really special thumbs. Thumbs move in lots of special ways and this makes them brilliant for things like gripping.
