Is it technology, or is it magic, that your windscreen wipers automatically turn on when it rains? How do planes stay in the air, how does sunscreen stop our skin burning?

Plus, we interview the president of Rural Women New Zealand, chat with the AA's Chief Mobility Officer, Jonathan Sergel and road test the Mevo carshare system.
