Book excerpt: Build 11 machines, includes all the LEGO bricks you need. From the 'practical' (a mechanical hand to pick things up for you) to the intriguing (a machine that makes crinkled paper) to the flat-out ridiculous (astronaut training for your mini-figures!), these projects encourage kids to explore the possibilities hidden in their LEGO collection. Inspires open-ended creativity to not just build the models in this book, but also to experiment with their own modifications to be faster, more accurate, or more complex.
