Scientist Nina and her young experimenters discover the amazing ways that things can change and react in the everyday world.

Nina investigates what metal is with the help of Luke, her sight neuron. Experimenters Cameron and Felix visit Nina in her science lab and use their senses to identify objects that are made of metal. Nina does an explosive experiment to show that different metals can behave differently in water or air.

Then they all go outside and search for things made of metal using a metal detector. They discover that lots of things like cars, bridges and boats are actually made from a metal mixture called steel which is extra strong. Finally, back in the lab, they do an experiment that shows that metals are special because they are good at taking and spreading heat - which is why radiators and cooking pots are made of metal.
