Jordan, Jaymee and Honor ask: How can an x-ray take a picture of my bones? With help from lovely Luke, the sight neuron, Nina shows the three friends a real x-ray machine in her workshop before packing her bag and taking them somewhere to see another one in action. They learn all about x-rays and make their very own x-ray machine using a torch.
