PRODUCT SUMMARY
For sale in U.S. and Canada only-- In Screws, inhabitants of Mammoth Island are in the process of building a new observation tower out of stone blocks when one of the islanders gets trapped at the top of the tower. With the help of a visiting gallant knight and his trusty mammoth, they are able to build a ramp around the circular structure and create a giant simple machine known as a screw. Turning the tower into a giant screw allows the islanders to spin the tower down into the soil, bringing the trapped Mammoth Island inhabitant close to the ground -- and saving the day! Part of the multivolume The Way Things Work DVD Series, based on the best-selling book by David Macaulay. A teacher's guide is included and available online.
EDITORIAL REVIEWS
"The series is humorous, informative and very educational. Explanations are clear and relevant, with neccesary diagrams to explain exactly how things work...These are exceptional physics videos that merit a place in all educational collections."- School Library Journal (August 2003)
