LEGO Chain Reactions

LEGO® Chain Reactions is packed with ideas, instructions and inspiration for building 10 different LEGO machines that spin, swing, tilt, roll, lift and drop.

Each machine works great on its own, but link them together and you can create amazing, fun chain reactions. Kids can also rearrange the machines in any order to design their own chain reactions.

The ideas were developed with experts, teachers and 11-year-old kids, with simple explanations of some of the science behind motion and interaction.

The set includes 33 special LEGO pieces to use with basic pieces from LEGO sets you already own, plus paper elements and helpful extras.
