Where do nature's building blocks, called the elements, come from? They're the hidden ingredients of everything in our world, from the carbon in our bodies to the metals in our smartphones. To unlock their secrets, David Pogue, the lively host of NOVA's popular "Making Stuff" series and technology correspondent of The New York Times, spins viewers through the world of weird, extreme chemistry: the strongest acids, the deadliest poisons, the universe's most abundant elements, and the rarest of the rare-substances cooked up in atom smashers that flicker into existence for only fractions of a second. Why are some elements-like platinum or gold-inert, while others-like phosphorus or potassium-are violently explosive? Why are some vital to every breath we take while others are lethal toxins that kill off their discoverers, as with Marie Curie?
