Synopsis

Can you make a skyscraper out of pasta? How about a rocket from meringue? As an engineer and a BIG fan of chocolate, Roma herself has often wondered whether a bridge could be made out of chocolate. This might sound impossible (and delicious), but you don't know until you try...

An interactive, hands-on exploration of science and the world around us, in a fantastically fun book for children aged 7+. With seven interactive building projects, kids will find out what is possible, while learning about the science behind awe-inspiring inventions. They will also get to meet some of the world's most innovative scientists, who dare to experiment with wacky materials to create something great.

Written by bestselling author and award-winning engineer Roma Agrawal, this book encourages kids to put some unexpected materials to the test. It's the perfect way to get kids excited about science - whilst having a WHOLE load of fun!

Reviews

Linda

This hands on, interactive book is perfect for curious children aged 7+ who love exploring how things work in the world around them. It's full of fascinating facts and fun activities and encourages creativity with just a little adult supervision.

Can you make a piano from wool? Or bubbles from slime? Even a rocket from meringue? With eight imaginative experiments, children can try out these unusual creations using everyday items in surprising ways.

The book is beautifully illustrated and designed, with clear instructions for each activity. One of the best challenges is building a bridge from chocolate, just make sure the adult helper doesn't eat all the materials before construction begins . . . oops!

How to Build a Chocolate Bridge is written by award-winning engineer Roma Agrawal and would make an excellent addition to primary school science lessons. It would be a brilliant way to inspire young minds, and show that science can be both educational and great fun.
