Motion sickness is also known as travel sickness, sea sickness or air sickness. It can happen in a number of situations, not all of which involve movement, and is a very unpleasant sensation. As part of our Have You Ever Wondered series, our Science Editor Sam finds out what causes motion sickness, and if there is anything you can do to prevent it.
One of the nicest things about being an author (apart from being able to go to work in your pyjamas) is being invited to talk about books in schools. I love chatting to enthusiastic pupils about all things bookish. Usually the questions I am asked are ones I can answer easily.
‘How long does it take you write a book?’
‘Where do you get your ideas from?’
‘When did you write your first book?’
But at a school last week a student asked: ‘What is your favourite book?’
Now that’s a tough one.
I’ve read so many good books, how could I possibly choose my favourite?
And what if I haven’t read my favourite book yet? Indeed, what if it hasn’t even been written?
Well, there is a nice little story attached to the name of the butterfly. In the past, there was a general belief that butterflies ate milk and butter. This probably came about because of the way that flies hover over any food at all that’s left out, and butterflies may have been seen hovering over uncovered pails of milk and butter. Not only that, but this belief developed to encompass the idea that butterflies were either sent out by witches to steal butter, or were in fact, witches themselves, disguised as butterflies. Quite why the witches were out to steal the butter, we don’t know!
