David Macaulay’s How Machines Work uses pop-ups and award-winning illustrations to demonstrate the technology of six simple machines.
Follow the mad antics of Sloth and his side-kick Sengi as they try to break out of the zoo with the help of levers, pulleys, screws, inclined planes, wedges and wheels.

Packed with engaging, hands-on activities, David Macaulay’s How Machines Work will gear kids up for scientific and engineering greatness!
This unique book by award winning author, David Macaulay, features two mischievous animals who try to escape from the zoo using machines. Machines are explained in detail as you follow Sloth and Sengi in their escapades. The cover of the book has a working simple machine that features principals learned in the story. The book is rich in detail and adventure and would make a great gift to put under the tree! I am giving my copy as a gift to a special family!


Escaping animals, eh. Once upon a time at the Como Zoo….
This would be fun for my kids! Their dad is an engineer and machinist so they frequently love to ask how things work!
This looks like lots of fun. I bet the kids would love it!
My sons would love this book! They get so excited driving by construction sites and what to know what everything does!
We have that book and just love it. There’s so much fun stuff to learn about that appeals both to kids and adults. Great holiday gift idea.
My son is all about trucks and tanks nowadays! He would love to check out this one.
