Every year between 10,000 and 60,000 tonnes of meteorites fall to Earth. Generally we think of meteorites as being large and heavy, but 95 per cent of those that fall to Earth are tiny - less than one millimetre in diameter. These are called micrometeorites.
This casebook will tell the story of how Museum scientists discovered a very unusual micrometeorite - the Cosmic football - and how its' billion year-old history was unravelled.
Get ready to join the Museum's scientists as they boldly go where no one has gone before...
