Walking on the plane.

Whoo-hoo!

On the plane.

Bye-bye, Boston.

Super excited!

Juan, are you super excited?

I can't feel my fingers.

He can't feel his fingers.

Are you ready?

Let's go!

All right, New Orleans!

It's so cool.

We're going to rock this

city.

All right, here we go!

Break it down, break it down!

Let's go in!

Nate's an alligator.

That one's cute.

It matches your outfit.

No, no, I like the vest.

I like the vest.

Dude, look at that horse.

Dude, look at that horse!

[harmonica playing]

Oh, very nice.

Oh, no!

Dude, that French Quarter was

ridic.

You guys, we're going to

swing by the firehouse to pick

up our client, Ryan, and he's

going to show us another part of

the city.

And then we're going to go try

out the boats.

Yeah!

All right?

Awesome.

All good.

Cool.

The architecture is really

cool.

The architecture here is so

cool.

What's up, Ryan?

Good morning, Design Squads.

How are y'all doing?

Good!

I'll take y'all down to Lower

Ninth right now.

Did a lot of rescues there

during the storm.

All right, sounds good.

Okay, sounds good.

Great.

During Katrina, where we're

going, the water was no less

than eight to ten feet at any

given point.

How many rescues did you

personally make?

That first day after the

storm, I... I... I was with my

crew.

I lost track after 67 within a

couple hours.

couple hours.

Wow.

And we were out there until

after dark, until about 10:00

that night, before it got too

dark.

And then the alligators were out

and it just... it became too

unsafe for us to be out there.

We had to pull back in.

The alligators were just

roaming around in the water?

Alligators, sharks, snakes,

dogs.

No way.

Wow.

All right, guys, we're coming

in to the Lower Ninth Ward right

now.

Currently where we're at, we had

probably close to 13, 14 feet of

water.

This van would be completely

submerged, and you could stack a

van on top of it, just to give

you an idea.

I... I... I remember, after the

storm, going through and... and

doing recovery missions.

There were just piles of houses

together.

Here we are at the house that I

did my first rescues at, and

we're going to actually meet one

of the girls that... that we

saved.

All right, guys.

Guys, this is Tiaria.

This is one of the first people

that we were able to rescue.

How are you doing, sweetie?

Fine.

Good to see you again.

Hey, Tiaria.

Hi, Tiaria.

Tiaria, could you tell these

guys what happened?

Okay, when the storm came, we

were inside, like, on the first

floor.

And as the water came, everybody

was having to go upstairs.

By the time you were upstairs,

the water was, like, basically

covered the whole first floor.

So it was really crazy.

And at nighttime, we just was

very scared because you didn't

have any lights, no power, no

food.

You can hear people shouting and

screaming "Help, help!"

This is the actual window where

we were rescued from.

Water was, like, covering the

whole entire roof right there.

I was really afraid, you know.

I didn't know what to do.

I thought it was over, you know?

I thought no one was coming for

us or anything.

You thought you were going to

die?

Pretty much, because, you

know, you didn't hear anything,

you know.

You couldn't.

There was no news, you know, no

telephones, no nothing to... to

communicate.

It's ridiculous.

What was your reaction when

you saw Ryan coming to rescue

you?

It was exciting.

You're a hero.

Yeah, Ryan!

Yeah, Ryan!

Well, Tiaria, thanks a lot

for telling us your story.

It's amazing.

No problem.

Thank you.

Nice to meet you.

Design Squads, you guys ready

to do what we came here to do?

Yeah!

Let's do it!

Let's go!

Show Ryan the boats.

Thanks again, Tiaria.

Bye.

It's nice to meet you.

Let's go, Design Squads.

So, guys, we set up a little

obstacle course over there where

we're going to perform the

actual testing.

Now, beforehand, we're going to

give you a little bit of time to

do a bit of a practice run, and

both teams has a couple of

things to finish up before we

run, right?

Yep.

Oh, and there's a real dog

coming to get rescued, all

right?

So be prepared for that, all

So be prepared for that, all

right?

A dog!

Yes, a real dog.

Let's get to it.

Let's go!

Tick tock, Design Squads.

Green Team!

So, I think it'd be a really

good idea to put some protection

over these propellers so that if

things are flying because of

winds or something, nothing's

going to get caught in the

propellers from behind.

That seems good.

That sounds reasonable.

I just drew on myself.

So you're going to fix that

propeller first?

Yep.

I felt like this challenge,

we actually knew... I mean, we

spent so much time planning, so

we knew exactly what we had to

do.

I think that divvying up the...

the responsibility has

definitely helped us and made,

you know, made us go faster and

stay within the time constraint.

I also know it was good for me

because I like to work by myself

a lot of times, especially when

I'm, you know, annoyed or

something like that.

So, that was definitely a good

way for me to kind of get a hold

of myself and... and kind of

work my own pace and get

everything done the way I needed

to.

All right, cool.

That looks good.

Yeah.

"NOFD," what is that?

"New Orleans Fire Department"?

Yeah, you got it.

That's so esoteric.

Juan, if we can get that

piece done, that'd be really

great.

I am so close to heat stroke,

I can taste it.

Why do you talk so much?

Sometimes it's necessary,

though.

Be useful.

Does that make any sense?

Maybe, maybe not.

Let's just focus on the

project.

The way a gator kills its

prey is by biting it and

spinning it.

And the way Juan kills his

prey is by talking them to

death, so I think the gator

would win.

It just works faster.

>>[laughs]

As far Annelise goes, I mean,

she wanted to get things done

quickly, and it kind of, like,

takes away the fun out of this

thing.

It got me... it didn't get me

angry; it annoyed me.

She just sucked out all the

energy out of the team.

I mean, working just for the

sake of working isn't what I do.

I try to have fun with what I

do.

All right, before we finish

the decorations, I think we

should test it just in case we

need to do any modifications.

All right.

All right?

Yeah, sounds good.

Yeah, that sounds good.

Got it, boys?

Yep.

They're testing.

They're ahead of us.

Let's go.

Don't think competition

really matters.

Looks nice, guys.

It looks very nice.

You guys ready?

Yeah, let's try this out.

[engine revving]

[engine revving stronger]

Is the right prop going?

[engine revving]

Nice!

Nice!

It looks good.

Can we get it to turn?

Turn right, turn right.

Nice!

Forward.

Yeah!

Go.

[engine stalls]

Something wrong with it.

The fire department had to save

our boat.

We'll just bring it in, and

then we'll change the fuse.

We'll change the old fuse.

Yeah, and that should work.

Yeah.

Purple team is right.

A fuse is a thin metal wire that

protects a device from too much

current.

Here's how it works.

When electrons flow through a

circuit, they create heat in the

metal wires.

The thinner the wire, the harder

it is for the electrons to move,

so more heat is generated.

When there's too much current,

the fuse acts like a weakest

link in a chain by heating up

more quickly than the other

components, and it melts.

That breaks the current flow and

protects the more expensive

components from damage by heat

or fire.

Purple Team pushed the throttle

too quickly, so the motors drew

too much current and the fuse

blew.

Let me check the fuse real

quick.

Yeah, it's... it's burned out.

All right, let me... let me

grab a new one.

A 30 amp.


Yeah.

All right, power's on.

All right.

That looks good.

Sweet.

Yeah, okay.

That looks good.

Nice.

"Amphibulance."

How is it amphibian?

It only works in water.

It just looks like one.

Does it really?

Let's go ahead and take it to

the water, guys.

Which way are we going?

Put it on top?

Yeah, just go over the top.

All right, that thing is

attached.

You guys ready?

Yeah, I'm ready.

Okay.

[engine revving]

It goes!

Are we steering?

Do we have steering ability?

Try to turn it, like, turn

it, turn it, turn it.

Turn it!

Turning... I'm turning.

Yeah, that rudder's all the way

turned.

That's definitely not

turning.

Here's why Green Team is

having trouble.

They're using a rudder to steer

their boat, and when the rudder

turns, it deflects water to one

side.

That creates a force that pushes

That creates a force that pushes

the rudder in the opposite

direction and turns the boat.

But here's the catch.

Since their rudder is too small

and has a small turning radius,

it doesn't deflect enough water

to create sufficient force to

make sharp turns, so the boat

turns wide.

Purple's boat is more

maneuverable because they use

the props to steer.

To turn, one prop pushes air

forward while the other pushes

air backward.

But because both props are wired

to the same throttle, they spin

at the same speed.

If they had wired each prop to

its own throttle, one prop could

spin faster than the other so

they could make small turns to

stay on course.

Instead, with both props running

at the same speed, there's too

much turning force, so Purple

team ends up zigzagging.

I would stop.

Stop, stop!

All right, quickly, in

reverse.

Yeah.

Can we go forward?

[clapping]

That looks good!

Look at it go!

Look at it go.

Whoo!

Let's get the dog.

A beautiful landing, Juan.

Beautiful!

Ours didn't blow up!

Drop anchor!

That was a successful test.

We are ready to go.

All right, we're ready to go.

Nice work, guys.

Are we good to go?

All right, Design Squads,

it's the moment you've all been

waiting for.

This is the final test for the

pet rescue challenge.

Are you ready?

Yeah!

Let's do it.

Now, Ryan's brought a special

guest he'd like to introduce.

This is Miss Heather Rigney.

She's the coordinator for

disaster preparedness with the

SPCA.

Hey, Heather.

Hi, Heather.

Hi, Heather.

How are you all doing today?

Good.

How are you?

And she brought along little

Mr. Lionel.

This is who we're going to be

rescuing today.

Okay.

Here's the drill, listen

carefully.

You're going to start on this

dock, you're going to drive the

vessel directly across to where

Heather will be waiting.

Heather's going to put Lionel

onto the craft, and you have to

drive an S-curve through the

debris on the way back.

Now, as soon as you get to this

dock, Ryan's going to take

Lionel in the cage off the

vessel and to safety.

Are there any questions?

No.

Let's do it.

Let's do it.

Let's roll.

Green Team, you're up first.

Yeah, all right!

Ana, you want to give Ryan

the rundown?

All right, Ryan, our vehicle

is called the Amphibulance.

Our inspiration was a catamaran.

So, it has two keels to

stabilize it, we have rudders to

move from side to side, and

it's really stable; it doesn't

flip.

And you can put a lot of weight

in it, and it'll still go.

So you ready to see it?

Sounds great.

Let's do it.

Let's do it.

There it goes!

That's beautiful.

Look at that thing go!

That's not sitting that low

That's not sitting that low

in the water, either.

No, it can take a lot of

weight.

Yeah.

Is the steering working?

Can you put it in reverse now?

All right, all right, you almost

got it.

I think ours maneuvers way

better than theirs.

Oh, yeah.

And it's... I think it's more

stable, too.

Yeah.

Our weight was distributed

really well.

Like, theirs... theirs is kind

of back-heavy.

Got it?

Slow and steady.

This controller's a little

iffy.

True that.

It's fine.

We have contact.

What do you think so far,

Ryan?

It got across the... the

canal.

See how it acts with some weight

in it now.

Mm-hmm.

All right, Lionel.

Uh-oh.

Yay!

He's not liking it.

Are we good?

Good to go.

Cool, cool.

Come on, Captain Lionel.

I don't want to scare the

dog.

There he goes.

Aww!

And our boat isn't even

submerged, like, at all.

It would... could take a lot

more weight than that.

How's Lionel doing?

Is he good?

He's chilling.

He looks okay from here.

You got to be gentle.

Oh, he's moving!

The dog is moving.

And look how stable it is.

He can't even shake that thing.

It's so awesome.

Shake it, Lionel.

Rock the boat, Lionel.

Rock the boat.

Dude, Lionel's a... like...

Lionel's a champ.

Lionel's a champ, man.

All right, here he comes!

Hey, Lionel.

Hi, Lionel.

Hi, puppy.

How was your trip?

Good boy.

Look at that, right to him!

There you go.

You are safe.

And we got a dog.

Nice job, Green Team.

Successful rescue.

Purple Team, you guys think

you're up for it?

Yeah!

Lionel, are you up for it?

Yeah, he is.

Purple Team, give us the

scoop.

All right, Ryan.

Well, this is our water craft,

and the structure is based on a

system of PVC pipes.

The bumper in the front moves

any obstacles out of the way,

and it also keeps it steady.

And another thing about the PVC

that we like is that it's

sturdy, and there's no risk of

anything getting punctured.

It's a good plan with the

PVC, and I also like that bumper

idea.

We have two propellers, one

on each side, and the cool thing

about them is that they're above

the water, so they have nothing

below.

So, you know, in case of a fence

or clothing floating around,

this won't get tangled up with

anything.

Show us.

Let's go.

Okay.

Yeah, there we go.

Oh, yeah!

Just go straight.

Just go straight.

I am going straight, dude.

This is straight.

Why don't you angle it a

little bit more left and just...

At least it's going to be

used in, like, a u-turn.

We're going.

There's Lionel.

From a scale of one to ten,

maneuverability was 100.

In fact, it was so high it

didn't let them do anything.

It took them so long to get

to the other side.

We did it faster.

Ours is really better.

Dog's in.

Come on, Lionel.

You good?

Dog's ready.

He looks so confused.

Come on, Lionel.

It's looking straight.

Look at that nice turn.

That was a sweet turn.

That is nice maneuvering.

Nice work.

And you are safe, my little

friend.

Whoo!

All right!

Nice work, Purple Team, on a

successful rescue.

Well, Ryan, have you seen enough

of both boats?

I think so.

All right, let's take a

second and talk about who's

going to win.

Sounds good to me.

Lionel!

Should we let him out?

So we had two successful

rescues.

The mission was accomplished

on both deployments.

Yeah.

So what do you think of Green

Team?

I... I wasn't terribly

impressed with maneuverability.

I think that... that "dogamaran"

style boat that they went with,

kind of... it held a little

straight a lot easier than

side-to-side.

They can maybe work on that a

little bit.

And the rudder system might not

work too well with debris in the

work too well with debris in the

water, and they'll have to kind

of work on that.

But, I mean, it did get the dog

back in a safe... safe way,

so...

I think our Amphibulance went

pretty straight, but

maneuverability-wise?

It took so long to build the

motors and rudders, much longer

than we thought.

And so we didn't have time to

test and to realize that the

maneuverability wasn't going to

be that good.

Because I think we felt pretty

confident in that rudder system,

right, Juan?

We did.

Well, heck, it was good.

It was... it...

I just said...

...turned.

It did turn eventually, but

it just didn't work as much as I

had hoped it would.

How about Purple Team?

Purple Team, I... I thought

it did a lot of spinning.

No, I wish it would just

go... go straight.

Yeah.

It's because we didn't get

enough practice with it.

If we had more testing, we

could have figured that out.

Almost too maneuverable.

Yeah, that's... that's...

It would take more driving

practice.

Exactly.

I think... I think with a little

practice, they could... they

could definitely do a little bit

better on that.

Mm-hmm.

I was highly impressed with

the PVC pipe, being that the

other one was inner tube.

And even though it's... it's

industrial-strength and... and

very tough, glass and sharp

objects-- which you're going to

see in the water-- could easily

puncture that.

So if you're going to use one

of these for pet rescue in a

disaster, which one would it be?

It was a good job.

Yeah.

We definitely went teamwork.

We had... we had a really

good time.

Yeah, we did.

Green Team's awesome.

It was lots of fun.

Let's go tell them the news.

Sounds good.

Hey, hey, hey.

Okay, Design Squads.

Hi, guys.

How's it going?

Ryan has reached a decision.

But talk about what you guys did

first.

Appreciate all the hard work

and effort.

I know you guys worked hard on

this for the last week.

And Green Team, I like that...

that "dogamaran" design.

It's good for going straight,

maybe not so much maneuvering

side-to-side.

Also, the inner tube system, not

really what... what would be

feasible in this situation, with

pointy objects-- glass, sharp

metals sticking up.

I mean, you have no idea what's

under these waters.

And this just would very easily

puncture, in... in my opinion.

Purple Team, that was a little

too maneuverable at this time.

It seemed to be spinning around

a lot.

That PVC pipe, though, worked

very well for... for keeping out

any kind of sharp objects.

If... if I was to go with a

decision right now, I'd have to

take Purple Team.

After we won, I feel... I

felt fantastic, because this is

our first win.

So, like, that's 100 points for

me, so I feel great.

Taking what I know now from this

challenge and applying it to all

the future challenges, I'm

definitely going to be on a

streak.

I'm going to be on a roll.

I'm going all the way.


member of Purple Team.

Congratulations.

All right.

Green Team, nothing for you.

We're going to shuffle it up

next week for the next

challenge.

Winning isn't always

everything.

And I know it sounds like spoken

like a true loser, but, as far

as I'm concerned, I'm in third

place.

It all comes down to the last

one.

The last episode, top... the top

two people with the highest

scores go head-to-head.

So all I got to do is get to

second place.

If I didn't have what it takes,

I wouldn't be here.

What do you say?

You guys hungry?

Yeah!

We are hungry.

Let's go eat some dinner.

Yeah!

Frog legs don't taste like

chicken, do they?

These are pretty good.

These are pretty juicy.

Let's go brainstorming.

Let's go brainstorming.

Let's go.

A win for Purple means that

Wes pulls ahead of Ana and leads

with 300 points.

Hey, Lindsey, there's so much

more action on our Web site.

Yeah, behind-the-scenes stuff

like our blogs.

Not to mention you can watch

full episodes.

Play games and build cool

projects.

Awesome.

Coming up...

We've got boys versus girls.

Whoo!

Girls belong in the kitchen.

The estrogen's too much for

him.
