(upbeat music) - Welcome back to What's Inside. I'm Lincoln and this is Dan. And today we have two really
cool statues right here. - We're at one of my favorite places and one of the most interesting places in the entire world, the
Hoover Dam in Nevada. This is the third in our
series, where we're working with the Department of
Interior and touring the National Parks and Monuments
around the United States. So today, they gave us special access. We're going so you the dam,
but places that you don't - You.
- get to go on the tour. They're taking us on a
special tour and showing us cool things that people don't usually see. Get ready for some awesomeness, let's go. Look down there Linc. - Whoa. (suspenseful music) - Do not fall down there
Lincoln, no leaning. (cracking) Off the tippy toes. Off the tippy toes. So there's a road that goes
right on top of the dam and curves around the arch part. There's the water and
then on the other side, you've got the other side of the dam, but then right here, just off the middle, you have these plaques
and this big metal door. This is where the elevators are. We're going down under. This is just an elevator room. Look at that. I feel like we're in a bank vault. - It's nice and cold in here. - It's like golden elevator,
and then outside the road. Oh there's the police,
hide from the police. (dramatic music) - That door's really cool. - Bye Lincoln see you at the bottom. Wait no. We dropped 500 feet in that elevator. We're definitely under water. I guess technically. - That's a cool tunnel. Echo. - That's good, that's good. So once we walk out of this
tunnel, we're going to be in the main station underneath. Cause you see the dam, it curves. This is where the power is generated. Come check this out. - Whoa. - [Dan] Giant turbines. Look right down there. - What is this place? - This is it man, this is how
two million watts of energy are produced a year. Water comes down, goes through the pipes, comes into these turbines,
spins the turbines and then is spit back out the other side. There's eight on the Nevada side and nine on the Arizona side, 17 in total. If here was all of a
sudden an increased need and somewhere the power customers said, we need more energy, within four seconds they can flip on one of those and energy can start going through. Now down here, this little tiny red one, it doesn't look like much. This right here, generates
all the power that's needed for the dam. This is a 1.2 ton copper
thing that goes right in the middle of the generator
and comes back down here with the magnets and
when thing gets spinning, that's what generates the power. And that's what's inside
of these giant generators. And these are some pretty big cranes, and they can hook things up
if they need to fix things or replace things. That's what it looks
like when they do open up the other valves and it spills out. It's the part of the tour
where Lincoln get a hard hat, put's it on. - Pullin' my hair. Ah, there we go. - Safety first. All right, so that's where
we were on the other side, the Arizona side. Now we have our hard hats
on because we're going down by the generators, the giant generators. Check this out. There's Lincoln. Lincoln, look how big
that is compared to you. There's the generator. - It doesn't really vibrate that much. It's kinda surprising. - It is surprising, there's a lot of power going through there right now. Oh! - [Man] That's what
gives out of the whole-- - That's the one that powers all the dam. - What's inside a giant
generator that generates power and electricity for
this entire dam structure. - This. - We just happened to be here,
when they're taking apart one of them. You have these giant
buckets that the water's going to push and spin
this around, which in turn, those are all magnets that go all around. This is it, you're seeing
inside of a giant generator right now. I can't believe we're here. - That's what's inside it. - That is. All right, I'm blown away. This is too cool. (dramatic music) This is a massive piece
of machinery right here. But this is where they come and they bring the turbans and they set them on here. You can see the grids
down here on the machine. So the turban will lock down into there and they can spin it. This giant machine will
actually come down and shave the turban, the turbine. Turban or turbine? I always say that wrong. - Turban. - Turbine. There are a lot of people
that are consistently maintaining this dam and
making sure that everything is flowing smoothly. I mean this is a crucial
part of the United States energy usage, pretty
much for Nevada, Arizona, and even California. There's your giant generators right there. The question is, what's
underneath the generators. What does it look like? We got our earplugs, I
guess it's going to be loud. (upbeat music) This looks like the permafrost tunnels, but right now, we're walking
into a cave tunnel with rock. - What is smells like? It smells like water. - [Dan] It does smell like water. There's a lot of water around us. - [Man] This is one of the
oldest dam tunnels we have. - [Dan] It only happens
when the toilets flush. - Oh nice. - [Dan] I'm just kidding. That's a good one. (dramatic music) Oh, look at that door. It's so dark I can't see that boat badge. A really cool door. All right, see you later buddy. Have fun over there. That is a moving door. Oh my gosh. - What? - This is it Lincoln. - [Lincoln] Wow. - Right now we are near the penstocks. They call them a penstock is the pipe, 30 foot in diameter,
that all the water goes through those four
towers, is fed into that, comes down, and then is
fed into the turbines and then it spits back
out on the other side. So pretty much every bit
of the Colorado River is all just from these pipes right here. This three inch diameter steel pin, it's keeping those pipes together. - It's hard to see how. - How heavy do you think this thing is? 30 pounds maybe? The Hoover Dam was completed in 1935, but they worked on it from 1931 to 1935. And it took buckets
and buckets of concrete that they had to keep pouring in there. Surprisingly, nobody was
buried in the concrete. One of the reasons why
this spot was ideal, was because the walls are all rock. And so they were able
to blast out and make these diversion tunnels. It's a lot of work. If this area started to
flood, the water pressure would push up against it
so much that it wouldn't, come open. Good-bye water pipe. If the water wasn't flowing
through the generators right now, and they needed
to have the water go out, they would open up these valves right here and this, on the other side of this wall, is where the water would be
shooting out of these pipes right here. - Oh, that's where we are. That's cool. - [Dan] Yeah. (light music) I can't believe we're down here right now. - Dad, that's a pretty cool shot. Wow! - [Dan] Oh my gosh. Lincoln, all of this water
that you're seeing right now go through the two penstocks. The one on that side and the
one that we just barely saw. All this water. - This is crazy. - Okay, we're going for this tunnel. Up above me is the air that
feeds the penstock tunnel where those pipes are. Wow, we're droppin' fast. - Yeah, very very fast. - We were on the top a few minutes ago, now we're at the bottom. (light music) Confined space do not
enter, permit required. - I touched the button. - [Fish] He touched the button. - I touched the button. I'm touching it. There you go guys. There's the penstock, the bottom of it. Hoo, we're down here guys, we brought you. (light music) We're on top of it. The giant pipe that is full of water. Where are we going now Lincoln? - I have no clue. - We're just walking in a
place that not many people have ever been. We're just walking through these tunnels. - Whoa. What's in there? - You don't want to know what's in there. That's where Batman lives. Look at that, there's like a rail track, so that if they need to
haul heavy things in here they could. Underneath the Hoover Dam. - Look at that bat. - Oh there's a bat, I told
you it was Batman's cave. Did I not just say that? There was a bat. Oh here it comes. Confirmed, this is Batman's headquarters. - Oh here comes another one. - Yep, there he goes. We're in this little tiny hallway here. What do you see Lincoln? Okay, this is a ladder
that goes to the bottom of the world. We're walking to the end of this tunnel. This is the last place
that we're going to. Check this out. - Oh wow! We're in one of those
little ventilation things. - We're in the ventilation
in the side of the dam. Guys, look at this. Look down below. We're actually in it right now. This is the vent. What's inside Hoover Dam? We literally are right now. We're in here! (light music) Oh, that was cool. (laughing) - That was not a good plan. - Good job at spitting in your own face. That's my son. (laughing) Okay, that's what this video's come to. So that's everything that you need to see inside of the Hoover Dam. This was a really special tour. - It was so awesome. - If you haven't seen our other two videos that we've done with the
Department of the Interior, this is our quest to go
and see the National Parks and the different things
that are public lands guys. These are, if you live
in the United States, if you want to see
this, this is your land. Go on a tour. Go visit these places and let
us know in the comments below what National Parks that you visited. Which monuments have you visited. Let us know where else should be go. What else should we see inside of. This is a great adventure. Thank you. - I think I've read
about these statues once. If you rub the toes
they give you good luck. Cause that's why they're all shiny. - [Dan] Like Neverending Story statue? There's the toes. Rub, there's soft and smooth. Rub it, rub the big toes. Do it Lincoln. The pinky, oh that's even better luck. Yeah, nice. Oh.
