How to Build a Chocolate Bridge: Extraordinary Builds Using Everyday Things

by Roma Agrawal, Robert Sae-Heng (Illustrator)

An interactive, hands-on exploration of science and the world around us, in a fantastically fun book for children aged 7+.

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...

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!
