LEGO Chain Reactions is packed full of ideas, instructions, and inspiration for 10 LEGO machines that spin, swing, pivot, roll, lift, and drop. Each machine alone is awesome, but put them together and you get incredible chain reactions. Then, combine the machines in any order you like to create your own chain reactions. Our team of experts worked with educators and 11-year-olds to invent the machines, then wrote a book that teaches the skills (and some of the physics behind the fun) kids need to create their own amazing chain reaction machines.
