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.

Written, produced and directed by Chris Schmidt, thius 116-minute documentary delves into the table of 118 elements.
Why are some elements like phosphorous or potassium are violently explosive?
Why are some elements vital to every breath we take while others are lethal toxins that kill off their discoverers as with Marie Curie?
This film takes you on a roller-coaster ride through nature's hidden lab and the compelling stories of discovery that revealed its secrets.
Amazing and amusing!

The graphics that were used to illustrate the points were great, the pacing is perfect, the explanations are rather quick, but the whole is significantly deteriorated by the downright goofy host and his childishness.

Well produced documentary. Interesting and easy to follow but maybe just a tad too easy.

Refresh course on the periodic table with emphasizes on rare earth, combustive and radio active elements. Well done in substance and humor. PBS has a nice summary of the Nova broadcast.

Even for a basic intro to the issue, there is too little science and too much schtick.

Very well done movie. A pleasure to watch. I would recommend this movie for all to see. No fast forwarding on this one. A++ DVD

Rare Earth part 4 (for more see Nova or PBS): DAVID POGUE: Apparently, my rocks are neo free.

But there was some good news. The ore I brought in contained a whopping 20 percent rare earth oxide.

Molycorp may soon be able to take a big bite out of China's near-monopoly...

PAUL CANFIELD: This is a rare earth magnet. This is actually neodymium, iron and boron. This is about 150 grams of the world's highest purity neodymium.

DAVID POGUE: Neodymium magnets are a bit of a misnomer. They're really iron magnets, with a pinch of neodymium added like a powerful spice to make them stronger, plus a few boron atoms to help hold everything in place.

You grow these? You don't dig these out of the ore, somehow?

PAUL CANFIELD: No, no, no. These don't exist in nature. These are things that we have to combine and cook, in the same way that huevos rancheros doesn't exist in nature; it has to be put together.

Rare Earth part 3: The truth is rare earths are not rare. They're just notoriously hard to separate. The problem is at an atomic level, the rare earth elements all look weirdly alike.

Moving from element to element, along a row of the periodic table, adds a proton to the nucleus and an electron to the outer shell, but in the rare earths, the new electron disappears into an unfilled inner shell. The result? Fifteen atoms that all have identical outer electron shells, making them virtually indistinguishable chemically.

But what about my rocks?

LARRY JONES: Okay, David, the ore that you brought us, the rocks that look like this, we analyzed those, and this is what we found: we found major components of cerium, lanthanum and praseodymium, but no neodymium.

Rare Earth part 2:

DAVID POGUE: I thought if we brought it here to Ames Lab, I thought you could do a little chemical analysis on it and tell me.

LARRY JONES: We certainly can.

Well, let's see.

DAVID POGUE: Yeah, watch out with that…

LARRY JONES: We'll take your favorite one and…

DAVID POGUE: Watch out with the hammer. What are you…?

LARRY JONES: See? Oh, yeah, there we go. That's a good piece right there. That's all we're going to need for the chemical analysis, so the rest of this we'll just…

DAVID POGUE: Yeah, but…

LARRY JONES: …throw it right here, in the trash.

DAVID POGUE: But, but that's, that's rare ear-, ah! California!

on rare earth part 1: DAVID POGUE: I brought this all the way from California.

LARRY JONES: All the way? All right!

DAVID POGUE: I carried it by hand.


DAVID POGUE: Because you know it's rare earth…

LARRY JONES: It's rare earth.

DAVID POGUE: …ore, and I didn't want anything to happen. I didn't check it. I didn't put it in the overhead.

LARRY JONES: Yeah, okay.

DAVID POGUE: I think I got some beautiful samples.

LARRY JONES: Oh, yeah?

DAVID POGUE: There's this mine in California, the largest one in the United States.


DAVID POGUE: Look at the size of this one.

LARRY JONES: Oh, yeah.

DAVID POGUE: I think this one's my favorite.

LARRY JONES: Oh, yeah.
