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

LEGO Chain Reactions
Design and Build Amazon Moving Machines
In a chain reaction, one thing leads to another, which leads to another, which leads to another, which. ..well, you get the idea
With the stuff in this kit and a pile of your own ordinary LEGO bricks, you can build Ten awesome machines that can be combined to make dozens of different chain reactions that use many steps to do. ..a whole lot of nothing (or maybe something vaguely useful).
Your machine could toss a gum wrapper into the trash, amuse your dog, deliver a message ('Oh Yeah!'), ring a bell, and generally make you the envy of the neighborhood.

Conclusion
LEGO Chain Reactions is a highly engaging and educational kit that combines the fun of building with the learning of basic physics principles. It is ideal for children aged 8 and up, providing an excellent platform for developing problem-solving and critical thinking skills. While the set's limited number of pieces may require supplementation for more elaborate designs, its compatibility with other LEGO sets makes it a versatile addition to any LEGO collection. Overall, it's a valuable tool for both learning and play, fostering creativity and innovation in young minds.
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!
