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. ## 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.ec/products/11531740-lego-chain-reactions](https://www.desertcart.ec/products/11531740-lego-chain-reactions) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-08-29*
