This bright, garish book tries to answer its title and other pressing questions for the young scientist aged 11-16. Do spiders have ears? Do rabbits fart? What do people taste like to sharks and tigers? Glenn Murphy from the Science Museum in London has tried to think of every awkward question posed to him and answer it wittily, but with straightforward science. 

The result is a book packed full of information that would not be out of place on a GCSE science paper. The topics covered are diverse ranging from the layers of the Earth ('Could you dig your way through the Earth to Australia?'), through the universe ('What is space made of?'), to digestion ('Why does your poo go runny when you get diarrhoea?').
