Product Description

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.

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 another… and another… and another.

Comes with: 78 page book, 33 LEGO elements, 6 LEGO balls, 6 feet of string, 8 paper ramps, 2 paper pop-up signs, 1 paper funnel ramp, 1 paper flag, 1 paper bucket, 1 platform

    This was not an easy concept for the authors and product planners to execute. It's radically different than just assembling Legos from an instruction booklet. A lot of thought and effort went into the chain reaction concepts and resulting projects. The book layout, the security so that the parts actually arrive at the consumer, the durability of the non Lego paper components, the directions on how to fold the paper components etc, etc, etc. are thoughtfully done. I think they struck a very good balance so this would not cost an arm and a leg. Some might call it cheap (a few Lego pieces, a beautiful well laid out instruction book with nicely printed paper components) but I call it cost effective. A lot of what you're paying for here is in my opinion is the wow factor of the book and the well thought out concepts.

    I supported my 7 year old grandson's effort to build the first project. My 5 year old grandson looked at what was involved and walked away I think because it looks complicated and the projects contain very few pieces. Both of them are very skilled Lego builders who pride themselves on their ability to throw lots of pieces together quickly. Does that sound familiar to you?

    So... I think what motivates most young Lego builders is assembling lots of pieces quickly and having a relatively static object to play with when done. The chain reaction projects aren't that at all. They don't look like much -to an adult - when complete. They are challenging in my view mostly because of the need for precision alignment between the paper parts and the Lego motion actuators the kids assemble to create the Chain the Reaction. Once assembled and aligned, making it function can require trial and error, motivation to succeed, precision hand and eye coordination and patience. I think that doing the first project successfully might be a make or break point for this product. Failure would surely be a deterrent towards doing subsequent projects in the book so initial success seems very important at least for younger children. The greatest joy my grandson experienced (and it was great joy) was the moment the first project functioned properly for the first time after several complete and partial failures (just as his patience was wearing thin) and then joy again once the chain reaction was rehearsed and easily repeatable so as to show his parents without failure. Having achieved this first success he was excited about doing more projects. It remains to be seen what his long term interest level will be.
    Yes.. This is radically different than just sticking prices together and success is not easy considering that the projects are minimalist in the total number of pieces. However I think the lessons and skills this product teaches are very important, worthwhile and noteworthy. Aside from the skills mentioned above this is also elementary physics of motion, weight, angle, momentum, etc. In summary, it appears that, assuming success along the way, the complicated chain reactions are fun for children to assemble, challenging to make fully, reliably functional and thrilling once they work for that first time. It's all good stuff!

Each step is a miniature lesson in the mechanics behind the chain reactions, making it an ideal educational tool for understanding cause and effect in a tangible way.

    The modular design of the Lego Chain Reactions components allows for a diverse range of contraptions, sparking the imagination of aspiring engineers to create their own intricate setups. The inclusion of Lego elements seamlessly blends the joy of play with the precision of engineering, promoting hands-on learning through experimentation and iteration.

    From a technical standpoint, the reliability and durability of the Lego pieces ensure smooth operation and easy troubleshooting. This kit not only fosters creativity but also hones problem-solving skills as users analyze and refine their designs to achieve optimal functionality.

    As someone who values the marriage of innovation and play, the Lego Chain Reactions kit is a testament to the power of hands-on engineering education. It instills a sense of accomplishment as intricate systems come to life, making it a must-have for anyone eager to delve into the fascinating intersection of Lego and engineering principles.

    So much fun! Younger kids will definitely need help with assembly, so that makes it a great family project! The instructions are mostly easy to follow, and the paper products are better than I expected. You WILL need many of your own Legos to build most of the projects. We have tons, and still had to make substitutions since there is much need for the 2x8 size. The only real downside (and reason it lost a star) is that you can't make all of the projects with the pieces provided- you will have to tear apart ones that you've already completed to make others since there are not enough special pieces to go around. I would be willing to purchase additional special pieces to be able to make them all and put them together for one awesome contraption! I haven't seen this available yet without having to purchase the whole book a second time. I wish it would have come with enough to make the whole book at once- I would have been willing to pay extra and it would be 5 stars for sure!
