Everyday low prices and free delivery on eligible orders. Review: Lego chain reactions - Bought for my 7 year old grandson who loves building with lego. He enjoyed helping to build the models. Even those that were described as easy, my grandson needed a lot of input from an adult. It states from 8 years, but I think adult help would still be needed, even for the easier models. It's also essential that you have a good supply of lego bricks, as additional bricks are needed. The models we have made so far, worked well. A good product, for children who love to build and create working models. Review: A great purchase - Has provided lots of fun for a Lego fan, and has added some further interest to a creative hobby. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | 7,421 in Books ( See Top 100 in Books ) 3 in Children's Books on Computer Hardware & Robotics 4 in Children's Books on Architecture 6 in Electronics & Communications Engineering | | Customer reviews | 4.5 4.5 out of 5 stars (22,987) | | Dimensions | 25.49 x 4.45 x 25.67 cm | | Edition | 1st | | Grade level | 3 - 4 | | ISBN-10 | 0545703301 | | ISBN-13 | 978-0545703307 | | Item weight | 454 g | | Language | English | | Print length | 48 pages | | Publication date | 1 Jan. 2015 | | Publisher | Klutz | | Reading age | 8 - 12 years | ## Images ![Lego Chain Reactions - Image 1](https://m.media-amazon.com/images/I/71ann8qnIhL.jpg) ## Questions & Answers **Q: What is the main age group this book is written for ?** A: My 10 year old daughter loves it and can use it independently. 8+ is the age recommendations on the box. **Q: Is this set too difficult for a soon to be eight year old? He has lots of legos, and loves building with them.** A: An 8 year should be able to build with it. It does require a lot of your own Legos. **Q: Does the lego classic medium creative brick box 10696 have everything i need to make all the machines?** A: I think you will need more. For example, the pop-up flag & falling hammer project uses 11 (2 of those included) 8x2's. One project also includes a 4 peg slope brick that I can't see in the picture of the brick box. For the pulley and bucket project, you'll need what looks like 28 4x2's (or pieces that add up to those). **Q: is this like traps** A: It's kind of a trap, but more like build and play with lego. You build something with lego and put it together. Then you will see a chain reaction. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Lego chain reactions *by A***R on 3 January 2025* Bought for my 7 year old grandson who loves building with lego.

It states from 8 years, but I think adult help would still be needed, even for the easier models. It's also essential that you have a good supply of lego bricks, as additional bricks are needed.

A good product, for children who love to build and create working models. ### ⭐⭐⭐⭐⭐ A great purchase *by C***R on 9 September 2025* Has provided lots of fun for a Lego fan, and has added some further interest to a creative hobby. ### ⭐⭐⭐⭐ Fun for a while but need your own bricks! *by M***R on 13 August 2020* I bought this for my son and we have spent quite a bit of time working on the various creations. I thought that the book was very well laid out and easy to follow. It comes with a selection of items but you will need to add bricks from your own Lego collection in order to complete the contraptions. We had a lot of fun doing this but my sons attention drifted by the mid point of the book and he hasn't revisited it since. I think he will, but it's one of those things that your kid will either fall in love with or only visit on a rainy day. ## Frequently Bought Together - LEGO Chain Reactions (Klutz Science/STEM Activity Kit), 9" Length x 1.06" Width x 10" Height - LEGO Gadgets (Klutz Science/STEM Activity Kit) 10.25" Length x 0.75" Width x 10" Height --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/48706427-lego-chain-reactions](https://www.desertcart.dk/products/48706427-lego-chain-reactions) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-23*
