Apparently more than three quarters of us have been stumped by questions including "where do babies come from?", "what makes a rainbow?", and "why is the sky blue?"

The survey was carried out as part of the Science (So What? So Everything?) campaign launched by the Government in January to improve science awareness.
Here are the trickiest questions. Feel free to give us your answers. (And no Googling them first. That's cheating.)
Why is seawater salty?
Why don't ships sink?
Where do bees go in winter?
Where does the sun go at night?
