Salt Mines

2nd December 2002 44 mins Season 9 Episode 57

It’s the only rock we eat – a priceless commodity essential to our very survival. It has over 14,000 uses – from de-icing our roads to softening our water. We dynamite it from vast caverns deep beneath the earth’s surface, harvest it via solar evaporation from seawater ponds, and mine it with huge hydraulic pipes penetrating to subterranean deposits. The world of salt…something to think about the next time you sprinkle that humble white crystal over your next meal.

Concept Cars

They were pure fantasy on wheels, machines designed to make the heart race and the mind ask…what if? Explore the world of 1950s concept cars–automotive art built to attract public attention, test wild engineering ideas, and give motorists a fleeting glimpse down the highway of tomorrow. Fasten your safety belt as we road test “rocket cars” like the aircraft-inspired 1951 Buick LeSabre, Cadillac Cyclone, Firebird I, and the original Corvette Stingray, and view Harley Earl’s visionary designs.
