LEGO Chain Reactions
Our book includes 33 special LEGO elements that combine with basic bricks from your collection to make your machines go. But don't worry that you won't have the right bricks; we worked with the folks at LEGO to make sure you'll need only the most common bricks, and that there are plenty of substitutes. The result is a chain reaction of fun, as one thing leads to anotherand#8212;and anotherand#8212;and another.
