How wide is the universe? What makes steak tough? Why does beetroot give me red urine? These tricky questions get stripped down in this Naked Scientists Question and Answer show. We'll be hearing about the camouflaged plant that doesn't need the Sun, a power plant that relies on osmosis and how the feeling of breath on your skin helps you to work out what sounds you're hearing. Also, in Kitchen Science, we use straws and a cup of water to show you how airbrushes and carburettors work!
