YOU AND I LIVE ON THE EARTH'S CRUST A THIN LAYER OF SOLID ROCK THAT'S ALL AROUND THE EARTH. NOW, WHAT'S UNDERNEATH THE EARTH'S CRUST IS DIFFERENT. IT'S MELTED ROCK, MOLTEN ROCK. NOW, HOW DO WE KNOW THAT? BECAUSE THERE ARE VOLCANOS.
1:36
LET'S SAY THIS LOAF OF BREAD IS LIKE THE EARTH. SEE... IT'S ROUND LIKE THE EARTH AND JUST LIKE THE EARTH IT'S GOT A THIN, HARD CRUST BUT UNLIKE THE EARTH WE CAN EASILY CUT THROUGH IT HERE IN THE LAB. ALL WE NEED IS THIS TABLE... AND THIS LABORATORY CHAIN SAW.
2:04
SEE, IT'S GOT A THIN CRUST, JUST LIKE THE EARTH. ALTHOUGH THE CRUST IS THIN IT'S THICK ENOUGH TO SUSTAIN LIFE. ALL LIVING THINGS-- ALL ANIMALS AND PLANTS, INCLUDING YOU AND ME-- WE ALL LIVE ON TOP OF THE EARTH'S CRUST. SO THAT'S GOOD. MMM. THAT IS GOOD. HOW DO WE KNOW WHAT'S UNDER THE EARTH'S CRUST IS DIFFERENT THAN WHAT'S ON TOP?
2:28
YOU EVER HEARD OF VOLCANOS? SO, LET'S TAKE A LOOK NOW AT THE: (<i> trumpet fanfare</i> ) SEE, IT'S SURROUNDED BY A THIN, HARD CRUST AND EVERYTHING IS ON TOP OF THE CRUST-- EVEN THE OCEANS ARE SLOSHING AROUND ON TOP OF THE CRUST. ISN'T THAT WILD? LET'S TAKE A LOOK AT WHAT'S INSIDE.
2:48
HERE WE GO. THERE YOU GO. THERE'S THE INSIDE OF THE EARTH. YOU GOT YOUR CORE RIGHT HERE, SOLID IRON. THEN THERE'S AN OUTER CORE-- THAT'S IRON AND OTHER METALS-- AND THEN THIS PART'S CALLED THE MANTLE. IT'S GOOEY LIKE HOT TAR. THEN OUT HERE, THAT'S THE CRUST. IT'S THIN AND COOL. THE CORE, THAT'S AROUND 1,500 DEGREES CELSIUS.
3:13
THE MANTLE, THAT'S AROUND 1,200 DEGREES CELSIUS. THAT'S WAY OVER 2,000 DEGREES. AND THEN THE CRUST, IT'S COOL AND HARD AS A ROCK. NOW, EVEN THOUGH THE EARTH'S CRUST IS REALLY THIN WE'VE NEVER BEEN ABLE TO DRILL ALL THE WAY THROUGH IT TO THE MOLTEN ROCK OF THE EARTH'S MANTLE. THAT'S WHY TO SCIENTISTS, TO SCIENTISTS LIKE YOU <i> VOLCANOS ARE SO IMPORTANT.</i>
3:36
THEY GIVE US SORT OF A WINDOW INTO WHAT'S UNDERNEATH THE EARTH'S CRUST.
3:42
I THINK THIS IS HER PLACE. WHY ARE YOU HERE? HI, JENNA. AREN'T YOU DOING YOUR SHOW? WE'RE RIGHT IN THE MIDDLE OF IT. I NEED A FAVOR. I'D LIKE TO BOIL AN EGG. AN EGG. OKAY, COME ON IN.
4:00
YOU'RE DOING THAT EGG-AS-THE-EARTH DEMONSTRATION, AREN'T YOU? YEAH, BECAUSE THE SHELL OF AN EGG IS A LOT LIKE THE EARTH'S CRUST. IT'S THE OUTSIDE, THE CRUST, AND INSIDE THE CORE, THE MANTLE ALL THAT HOT STUFF'S HAPPENING ONLY KILOMETERS UNDER OUR FEET, RIGHT? YEAH, RIGHT.
4:19
SEE, IF THE EARTH WERE LIKE AN EGG THE EARTH'S CRUST WOULD BE ABOUT AS THICK AS AN EGGSHELL. THE WHITE IS LIKE THE MANTLE AND THE YOLK IS LIKE THE CORE. BUT WE CAN EAT THE EGG. THAT'S RIGHT. SCIENCE IS GREAT. AND NOBODY COOKS AN EGG OF SCIENCE LIKE YOU DO, SCIENCE GUY. OH, GOLLY, JENNA.
4:36
DON'T YOU HAVE A SHOW TO GET BACK TO? OOH, UH, YEAH.
4:45
Announcer: New ways to roast weinies on the next <i> Bill Nye The Science Guy.</i>
5:11
RICHIE EAT YOUR CRUST.
5:19
EAT YOUR CRUST, RICHIE.
5:27
SON, EAT YOUR CRUST.
5:45
<i>SO, WE'RE STANDING IN A VOLCANO.</i>
5:52
YOU'RE ADDICTED TO VOLCANOS. WELL, I AM. THEY'RE ONE OF MY FAVORITE THINGS.
5:59
I'M A GEOLOGIST AND MY SPECIALTY IS VOLCANOLOGY. NOW, WHERE ARE WE, DAN? WELL, BILL, WE'RE STANDING IN THE CRATER AT MOUNT ST. HELENS INSIDE OF WHAT USED TO BE THE VOLCANO BEFORE 1980.
6:13
THIS IS AN EXPLOSIVE VOLCANO.
6:16
IT BLEW UP, JUST BLEW UP. IT'S NOT ONE OF THOSE OOZING, HOT ROCK, HOT LAVA VOLCANOS, NO.
6:25
IT BUILDS UP AND BUILDS UP AND... (<i> imitates explosion</i> )
6:30
MOUNT ST. HELENS WAS ERUPTING WHEN SOME OF THE FIRST PIONEERS AND SETTLERS CAME OUT TO THIS AREA. MOUNT ST. HELENS ERUPTED OFF AND ON FROM 1800 THROUGH ABOUT 1857. IT COULD ERUPT AGAIN. AND IT WILL.
6:47
IT'S A VERY YOUNG, VERY ACTIVE VOLCANO. IT'S BUILDING ITSELF UP AND THEN DESTROYING ITSELF. IT'S GOING TO ERUPT AGAIN. WE DON'T KNOW EXACTLY WHEN.
6:59
THERE'S TWO KINDS OF VOLCANOS-- SOME THAT OOZE MOLTEN ROCK AND OTHERS THAT EXPLODE. OH, SORRY.
7:11
SO, WE'RE ABOUT TO SET OFF OUR LABORATORY SCALE MODEL VOLCANO OF SCIENCE. (<i> trumpet fanfare</i> ) WHAT WE'RE GOING TO DO IS MIX SOME CHEMICALS TOGETHER THAT WILL CAUSE GAS TO FORM IN A LIQUID. THIS IS VERY SIMILAR TO WHAT HAPPENS IN REAL VOLCANOS. THE GAS BUBBLES FORMING IN THE LIQUID HELP DRIVE THE LAVA OUT OF THE CONE OF THE VOLCANO.
7:35
PRETTY WILD. SEE, AS THE LAVA RUNS DOWN THE SIDE OF THE VOLCANO IT BUILDS UP THE CONE, MAKING IT THICK. THIS IS WHAT HAPPENS IN REAL VOLCANOS. NOW, THE WAY WE MADE THIS LAVA HERE IN THE LAB WAS MIXING VINEGAR AND BAKING SODA. THEY'RE CHEMICALS THAT YOU CAN GET IN A GROCERY STORE AND THEY MAKE CARBON DIOXIDE GAS.
7:57
IT'S THE SAME GAS YOU FIND IN SOFT DRINKS. SEE? PRETTY COOL.

MAGMA IS HOT.
9:11
WE HAVE SOME MAGMA HERE IN OUR MAGMA OVEN OF SCIENCE.
9:28
WHEN I SAY "HOT"
9:31
I MEAN HOT.
9:35
THIS IS A FEATHER.
9:39
HOT. GOOFY KITCHEN FISH MITTEN.
9:47
HOT. A WIENER. (<i> dog yelping</i> )
9:55
THAT IS ONE<i> HOT DOG.</i> NOW, THE WHOLE EARTH IS THIS HOT, OR HOTTER EXCEPT FOR A THIN, COOL LAYER THAT WE CAN WALK AROUND ON. THAT'S THE CRUST. WHOA.
10:14
DO YOU GUYS REALIZE WHAT YOU'VE JUST BEEN WALKING OVER?
10:23
THE GUTS OF MOUNT ST. HELENS, THE INSIDE OF A VOLCANO. <i> 40,000 YEARS OF ROCKS</i> <i> CAME SPEWING OUT</i> <i> AND FILLED UP THIS VALLEY.</i> <i> WHAT WE'RE GOING TO DO TODAY</i> <i> IS WE'RE GOING</i> <i> TO START MONITORING</i> <i> THE BIOLOGICAL RECOVERY.</i> <i> THE VOLCANO</i> <i> ACTUALLY CREATED HABITAT</i>
10:41
<i> THAT'S ALLOWED A LOT OF LIFE</i> <i> TO COME IN AT GREAT NUMBERS.</i> THEY'RE FLOURISHING.
10:47
<i> I CALL THIS</i> <i> THE REASSEMBLY OF LIFE</i> <i> BECAUSE ONE PIECE BY ONE PIECE</i> <i> ALL THE PLAYERS</i> <i> ARE COMING BACK IN.</i> IT'S GETTING INTERESTING ON THE VOLCANIC LANDSCAPE. <i> THERE'S SO MUCH GOING ON.</i> Richie, eat your crust.
11:07
Son, eat your crust.
11:15
HOT! VOLCANOS, GEYSERS, HEAT FROM UNDER THE EARTH'S CRUST.
11:21
HOT! THIS IS A GEYSER. IT'S JUST LIKE A VOLCANO EXCEPT INSTEAD OF ERUPTING WITH MELTED ROCK <i> OR HOT LAVA</i> IT'S BOILING WATER AND STEAM.
11:34
THE ENERGY COMES FROM THE SAME PLACE UNDERNEATH THE THIN EARTH'S CRUST.
11:48
GEOTHERMAL SCIENCE!
11:51
YOU CAN MAKE YOUR OWN GEYSER RIGHT AT HOME. LIKE ANY GEYSER, THIS INVOLVES VERY HOT WATER SO BE SURE TO HAVE AN ADULT AROUND. YOU'LL NEED A HEAT-RESISTANT GLASS FUNNEL... Bill: IF IT'S GLASS, IT'S HEAT RESISTANT. HENCE THE TERM, "HEAT-RESISTANT GLASS." ...AND A POT TO BOIL THE WATER IN.
12:09
THIS KIND OF GEYSER LOOKS THE COOLEST IN A GLASS POT. SET THE FUNNEL IN THE POT AND GET THE WATER BOILING. THE TIN FOIL ACTS LIKE THE EARTH'S CRUST. IN A FEW MOMENTS, YOU'LL HAVE A GEYSER. THE WATER BOILS IN THE BOTTOM OF THE POT MAKING WATER VAPOR. THE VAPOR EXPANDS AND FORCES WATER OUT OF THE TUBE
12:29
BUT THE WATER DOESN'T COME OUT ALL AT ONCE LIKE A HOSE. INSTEAD, IT PULSES. IT ONLY SQUIRTS ONCE IN A WHILE. THE SAME IS TRUE IN THE EARTH <i> LIKE OLD FAITHFUL.</i> THE PRESSURE BUILDS UP AND FORCES WATER OUT OF THE GROUND. NOT THAT BAD.
12:49
Sc-sc-sc-sci-sci-sci... ...EN-EN-ENCE! SCIENCE. SCIENCE... S-S-S-SCIENCE.
12:58
HELLO, TODAY ON<i> CONSIDER THE FOLLOWING</i> I'D LIKE YOU TO... CONSIDER THE FOLLOWING.
13:06
YOU AND I ARE SITTING ON THE EARTH'S CRUST AND IT SEEMS PRETTY SOLID, DOESN'T IT?
13:13
BUT NOW SCIENTISTS BELIEVE THAT THE EARTH'S CRUST IS ACTUALLY MADE OF PLATES. NOT CHEAP, PLASTIC PICNIC PLATES LIKE THIS...
13:23
BUT TECTONIC PLATES. AND "TECTONIC" IS FROM THE LATIN WORD FOR "BUILD." SO THE EARTH'S CRUST IS BUILT OF PLATES.
13:33
AND THE PLATES ARE FLOATING ON THE EARTH'S MANTLE WHICH YOU KNOW IS MOLTEN METAL. IT'S KIND OF LIKE CORN SYRUP. SCIENTISTS ACTUALLY USE CORN SYRUP TO DO STUDIES OF WHAT'S UNDERNEATH THE EARTH'S CRUST. SCIENTISTS FIRST CAUGHT ON TO THE IDEA OF TECTONIC PLATES WHEN THEY REALIZED HOW WELL SOUTH AMERICA SEEMS TO FIT IN NEXT TO AFRICA. HMM. NOT THAT BAD. SO TAKE A LOOK HERE.
14:00
HERE WE HAVE THE CAMP STOVE OF SCIENCE. (<i> fanfare</i> ) AND IN IT WE HAVE MODELS OF TECTONIC PLATES. SEE RIGHT NOW, THEY'RE ALL TOGETHER. SCIENTISTS BELIEVE THAT AT ONE TIME ALL THE PLATES OF THE EARTH'S CRUST WERE ONE PIECE, CALLED PANGAEA AND PANGAEA, WELL, THAT MEANS "WHOLE EARTH."
14:21
SEE? NOT THAT BAD. LET'S SAY THIS IS THE EARTH'S CRUST. YOU SEE WHERE THE PLATES-- THE TECTONIC PLATES-- ARE SPREADING APART THAT'S WHERE WE GET VOLCANOES.
14:33
AND WHERE THEY COME TOGETHER THAT'S WHERE WE GET MOUNTAINS. NOW, YOU KNOW, THE PLATES ARE STILL MOVING, EVEN TODAY. IN FACT, NORTH AMERICA IS MOVING AWAY FROM EUROPE ABOUT THIS MUCH EVERY YEAR. ABOUT AN INCH EVERY YEAR. WELL, THANKS FOR JOINING US ON...
14:53
<i> CONSIDER THE FOLLOWING.</i>
15:01
(<i> hissing</i> ) OKAY, IT'S REAL IMPORTANT <i> TO HAVE SHADES ON IN HERE</i> BECAUSE SOMETIMES THINGS WILL POP.
15:14
THIS IS MOLTEN GLASS. WATCH WHAT HAPPENS. Children: OOH!
15:22
Eckstrand: <i> WE'RE MAKING A VOLCANO</i> <i> MADE OUT OF MOLTEN GLASS.</i> <i> YOU WILL SEE,</i> <i> THE MOLTEN GLASS</i> <i> IS EXACTLY THE SAME</i> <i> AS THE LAVA.</i> <i> IT'S MOLTEN FLUID.</i> <i> VERY, VERY HOT.</i> <i> BUT WHEN IT COOLS DOWN</i> <i> IT WILL BE HARD AS A ROCK.</i> <i> THE SAME AS VOLCANIC GLASS.</i>
15:41
KA-BOOM.
15:44
<i> I RECKON THAT'S JUST ABOUT</i> <i> THE RIGHT TEMPERATURE</i> <i> FOR MARSHMALLOWS.</i>
15:51
NOW THE EARTH'S CRUST IS PRETTY THIN BUT COMPARED TO YOU AND ME, IT'S PRETTY THICK AND SOME PARTS OF IT CAN GET HOLLOW. LOOK AT THIS-- WE'RE IN A CAVE IN A MOUNTAIN IN MONTANA. NOW, THIS CAVE STARTED OUT ABOUT 300 MILLION YEARS AGO WHEN AN ANCIENT SEA LAID DOWN A LAYER OF LIMESTONE. IT'S LIKE CHALK.
16:13
JUST THE OTHER DAY, ABOUT 3½ MILLION YEARS AGO A RIVER WAS RUNNING THROUGH HERE AND IT HOLLOWED IT OUT. NOW, CHECK THIS OUT. THE EARTH'S CRUST HAS COOLED SO MUCH AND BECOME SO RIGID IT CAN SUPPORT THE CEILING OF A HUGE ROOM LIKE THIS. ISN'T THIS WILD? SO... STALACTITE, STALAGMITE. TITE, MITE, TITE, MITE.
16:38
SO CASS, WHAT DO YOU DO? I MINE FOR SAPPHIRES IN THE EARTH'S CRUST. RIGHT AROUND HERE? RIGHT AROUND HERE. HOW DO WE GET THEM OUT? WE DIG AND WE NEED A SHOVEL, A PICK, AND A SCREEN. AND THE BIGGEST PERSON DIGS. THAT WOULD BE ME? THAT WOULD BE YOU.
16:58
WHEW! THIS AIN'T EASY.
17:01
THIS IS SOME TOUGH CRUST.
17:06
MIGHTY TOUGH CRUST.
17:20
NOW IT'S TIME FOR THE HARD PART. THE HARD PART? Thompson: <i> THE HARD PART.</i>
17:30
THIS IS THE HARD PART. KEEP SHAKING. THE SAPPHIRES WILL FALL TO THE BOTTOM.
17:39
LET'S SEE WHAT YOU GOT.
17:45
Nye: WOW! Thompson: THE SAPPHIRES WOULD BE IN THE DARK AREA. THIS IS A SAPPHIRE BEFORE IT'S CUT. Thompson: AND THIS IS A SAPPHIRE AFTER. COOL! Nye: VERY COOL!
18:00
SHIFTING TECTONIC PLATES CAUSE EARTHQUAKES. THE PLATES ARE ALWAYS MOVING. IF YOU WERE STANDING HERE YOU'D BE SAYING...
18:11
Girl: <i> THIS IS A DEVICE</i> <i> THAT MONITORS EARTHQUAKES.</i> <i> IT'S A SEISMOGRAPH</i> <i> AND IT DETECTS EARTHQUAKES.</i> <i> SOME EARTHQUAKES ARE SMALL</i> <i> SOME ARE VERY BIG,</i> <i> AND SOME ARE HUGE. WHOA!</i> HERE'S A COOL TRICK YOU CAN DO TO SHOW YOU HOW SCIENTISTS KNOW THE EARTH'S CORE IS SOLID. LET'S SAY THIS IS THE EARTH.
18:31
NOW, WHEN AN EARTHQUAKE HAPPENS SOMEWHERE OVER HERE PEOPLE FEEL IT ON THE OTHER SIDE OF THE EARTH, WAY OVER HERE. LET'S SAY WE CUT THE EARTH IN HALF. WE'D GET WHAT? RIGHT-- A CIRCLE. MAYBE A CIRCLE LIKE THIS ONE. ROGER, YOU READY TO HELP? ROGER. LET'S SAY THIS CAN IS THE EARTH'S CORE
18:52
AND THIS FLASHLIGHT IS LIKE AN EARTHQUAKE HAPPENING SOMEWHERE IN THE WORLD. LET'S SAY RIGHT HERE-- ROGER? IT'S LIKE PEOPLE ON THE OTHER SIDE OF THE WORLD FEELING EARTHQUAKES. I CAN'T SEE THE LIGHT. AS I COME OVER HERE, I CAN. SO HE MAKES A MARK. I COME HERE AND I CAN STILL SEE IT. SO HE MAKES ANOTHER MARK.
19:16
SAY THERE'S AN EARTHQUAKE SOMEWHERE ELSE. LET'S SAY, OVER HERE.
19:22
I STILL CAN'T SEE IT IN THE MIDDLE BUT I COME HERE, I CAN SEE IT. SO ROGER MAKES A MARK. AND I COME OVER HERE AND SEE IT AGAIN. AND MAKES A MARK. NOW WE'RE GOING TO DO WHAT SCIENTISTS CALL CONNECT-THE-DOTS. HERE YOU GO. LET'S START WITH OUR SECOND EARTHQUAKE.
19:40
THIS WOULD BE LINE NUMBER ONE. NUMBER TWO AND NUMBER THREE AND LINE NUMBER FOUR. LOOK, NOW WE HAVE THE SAME SHAPE AND SIZE AS THE CAN. Nye: <i> SCIENTISTS FIGURE</i> <i> IF THE EARTH WERE LIQUID</i> <i> ALL THE WAY THROUGH</i> <i> WHEN AN EARTHQUAKE HAPPENS</i> <i> ON THIS SIDE</i>
20:01
<i> PEOPLE WOULD FEEL IT</i> <i> ON THIS SIDE.</i> BUT THAT'S NOT WHAT HAPPENS. SOMETHING BLOCKS THE EARTHQUAKE WAVES. THAT'S WHY SCIENTISTS FIGURE THE EARTH HAS A SOLID CORE AND FROM HERE TO HERE, IT'S 2,800 KILOMETERS. THAT'S FILTHY.
20:21
Woman: EAT YOUR CRUST, RICHIE.
20:27
RICHIE, EAT YOUR CRUST.
20:49
RICHIE, YOU SHOULD HAVE EATEN YOUR CRUST. (<i> pop dance beat</i> )
