Explore the substance that is almost literally the foundation of everything in our world with this fascinating look at the hard stuff.
- On one side you've got your Hard Place, and over here you've got your... well, you know.
- For over a decade, MODERN MARVELS has brought grand stories to life.
- The ultimate celebration and investigation of engineering excellence.
Celebrating ingenuity, invention and imagination brought to life on a grand scale, MODERN MARVELS® tells the fascinating stories of the doers, dreamers and sometime-schemers who created everyday items, technological breakthroughs and man-made wonders.
From the Stone Age to the Space Age, our world has been built on and from rocks. MODERN MARVELS® makes easy work of a hard subject in this fundamental and absorbing investigation of ROCKS.
Visit the Johnson Space Center in Houston to examine America's horde of moon rocks to see how the planets were formed and learn how old the solar system is. Watch marble and granite laboriously extracted, cut and polished. Do some blasting at a gravel pit, watch ore turn into steel and, finally, learn how the Geysers in Northern California harness heat from rocks to create energy for 85,000 homes.
Needless to say, this MODERN MARVELS® DVD, um, ROCKS!
