Would you like to make a trip to the Moon, or build your own nuclear reactor? Have you ever wanted to travel through time? Well, here's your chance! Whether you're interested in cloning budgies or building black holes, the "How to" guides will tell you everything you need to know. These hands-on guides give you step-by step instructions on how to build a Moon rocket, clone a sheep, split the atom or make a time machine. And on the way to becoming a time traveller or
nuclear genius, you can learn about the brilliant scientists who first made these incredible discoveries - and about the slightly less brilliant scientists who didn't.

How to Build a Time Machine tells you everything you need to know to make your own time machine. The work of Einstein showed that time is not fixed: it can be stretched or compressed. And black holes, which are formed when huge stars explode, could give us a way to travel through time. Use this book to experiment with gravity, investigate worm holes - and build a working black hole!
