Beskrivelse
Why do cameras use batteries so quickly? Why does warmth help a battery last longer? How do humans survive lightning strikes? We tackle these questions as well as reveal how steel ships protect themselves from erosion, whether stainless steel really is stainless, investigate the different types of salt and discover how lie detectors work!
