STEM Fun in Motion... LEGO with a Twist!
I got the LEGO Chain Reactions Kit for my boyfriend’s 11-year-old, and it was an instant hit. He’s already a big LEGO fan, but this took his building skills to a whole new level. The kit shows how to turn regular bricks into moving machines that actually do things, like kick a ball or send a message. The instructions are clear and super engaging, with just the right balance of challenge and fun. It also teaches some cool STEM concepts without feeling like homework. He got really into experimenting with the designs and even started inventing his own. If you’ve got a kid who loves building and figuring out how stuff works, this is a perfect choice. It’s creativity, engineering, and fun all in one box. Highly recommend!

Book
Be aware that what you’re really paying for here, is the book. There are a few Legos included and a couple of the projects can be done with only a few extra to add to those, but several of the projects also require a lot of extra Legos. So unless you have a large set at home, you won’t be able to make several of the projects. The projects are decent, though I can definitely see younger kids needing assistance. Personally, I don’t feel the cost is worth it, but if you get on a good sale price and have a Lego enthusiast at home, I’d pick it up.

Well executed by the authors. Think about these things before purchase.
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!

This was sent to my Grandson as a Xmas gift. He likes building and planning his project at a young age. He enjoyed the challenge of putting this together. It’s an interesting gift for boy or girl who like an engineering type of puzzle.

Not much bricks.

Purchased for my 10 year old Lego obsessed nephew - he loved it! Gave him a new challenge rather than always building kits.

al mio bimbo è piaciuto moltissimo!! Anche se è solo in inglese è molto intuitivo e riesce a costruire tutto da solo
