## Description

Lego Chain Reactions : Murphy, Pat: desertcart.ae: Toys

Review: It will keep your child busy for hours - My 5 year old loves creating chain reactions. This was a wonderful Christmas gift. Even though an adult supervision is required, you must allow the kids to read the book and create their own chain reactions. I was surprised to see my 5 year old go step by step and build the machines. Of course, you need extra Lego's This is just an addition.
Review: Good - Very few pieces. But this works with most other Lego pieces and good work for the brain to try create, record different types of reactions.

## 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.
