Thanks.

Okay, guys, so we have a lot

of things to fix.

There was a lot of, like,

twisting, especially on this

end, right, guys?

Yeah.

Yeah, we should add those ankle

brace supports.

And also, we need to stiffen

this up, because it wasn't

giving any support.

We don't have that much time,

so we kind of have to divide the

tasks.

Yeah.

These poles right here are

getting stuck in the ground, so

Ill cut these off, trim these

down over here.

Okay, let's do it.

So the other thing that we

talked about was making the

brakes, right?

Mm-hmm.

What if we make it out of the

hollow half of a PVC tube?

Because it has the right angle.

So we push down the PVC, it

would go like that.

Good idea.

I think we're doing okay.

We're going to be crunched for

time at the end of the day

today, but if we work hard,

we'll be able to make it.

What do you think?

The smaller one?

I think once we cut it in

half, we can sort of curve it to

make it narrower.

That's how you do it!

Well, what did you think

about this?

It's a perfect fit.

It's kind of amazing.

That's going to help a lot.

Once we get some more

supports we'll be all right.

This works out really nicely,

dude.

Really stiffens it up.

It's definitely a lot thicker.

Doesn't bend as much in the

center.

After the tests, I lost a little

confidence, because it was

really wobbly.

really wobbly.

But after putting on the

reinforcements underneath, I

think it helped a lot.

All right, so pretty good.

Yeah.

So other than the handle,

what else do we have to do?

Weren't we going to do some

kind of a footbrake?

What do you guys think?

I think that's good.

I'm going to go outside and

look at the sled and see what we

can come up with for the foot

stop.

What I was thinking, I had

this aluminum, and it bends

upwards and attaches to this PVC

pipe.

How are you going to bend it?

With my bare hands.

We have an ambitious one over

here.

I'm going to try this.

So I have this piece of metal

right here, and it attaches onto

the steel plate I added.

And then underneath it goes the

PVC.

When someone steps on it, it

bends down and stops it, but it

springs back up, because this

aluminum is very springy.

I'm planning on riveting the PVC

on it.

Using rivets is a good way to

go, because rivets are strong,

lightweight fasteners.

Annelise is using pop rivets.

Here's how they work.

A rivet has a shank and a

mandril.

The rivet is inserted in a hole

drilled through two materials.

A rivet g*n pulls on the top of

the mandril, expanding the

shank.

As the shank expands, pulling on

the mandril clamps the two

materials tightly together.

The force from the g*n then

snaps off the mandril head at a

premade break point.

It's called a pop rivet because

of the sound the head makes when

it snaps off.

How's the riveting going?

That looks nice-- very, very,

nice.

Thanks, Juan.

All right, guys, I was just

looking at the sled outside, and

the foot stop is adjustable.

It goes down.

But once you're done using it,

you take it back up into place.

So we have to have something

that can facilitate that motion.

Green Team plans to slow down

their dog sled with friction

from a drag plate.

Friction is a force that resists

motion between two surfaces-- in

this case the ground and the

plate.

The greater the force applied to

the drag plate, the greater the

friction between the plate and

the ground.

And that decreases the forward

motion of the sled.

Since the friction force is

greater than the pulling force

from the dogs, the sled stops.

And Wes is right-- they must

also be able to lift the drag

plate so they can decrease the

amount of friction and

accelerate the sled.

And I found these strips of

metal right here.

What we can do is bolt one here

and then connect it to a plate.

and then connect it to a plate.

And this plate can be bungee

corded right here, just so it'll

pop back up once we're done

using it.

Do you think this is sturdy

enough, though, or...

I think so, yeah.

While you do that I'm going

to finish working on the

steering system so that I can

make it sturdy.

I'm going to use these plates,

and I'm going to bolt them in

here and here so that it cannot

move forwards.

And we're just not going to tie

the bolts all the way, so that

it can move from one side to the

other.

Okay.

That's really good.

Hey, guys, I want to build

the stand, where you stand.

I want to make it out of this.

And Lindsey, you think you can

weld it on?

Yeah, but I thought we were

done.

So why don't you cut it, and

then depending on the amount of

time we have left, we can decide

whether we're going to weld it

or bolt it.

We have two hours.

I'm done.

These are the ski plates that

the guy actually stands on.

So one of them will go here and

one of them will go here, and he

stands on them.

He stands on this.

Awesome.

That looks so good.

Yeah, yeah.

Do you want to work on this,

then?

Sure.

This is going to be under.

Bolt, like, one here, one here.

Yep.

All right.

It's all you.

Zach was really moody this

afternoon.

He was just kind of plowing

through everything, just

carelessly drilling.

I'm not really sure what his

deal was, but me and Ana work

together pretty well, and we'll

kind of just let Zach go on and

do his own thing while me and

Ana work together on the main

build.

I think that's good.

[laughing]

Sorry.

You all right?

Yeah.

Zach, come on.

You can't be in a bad mood.

My bad.

I was screwing a bold on the

handle, and I accidentally

flipped it and hit him in the

arm.

And I guess he got angry and

just walked out.

The last thing he needed was

The last thing he needed was

for you to... seriously.

He's a big boy.

He can make his own decisions,

choose how he acts.

What's good about this rope

is it can pull, like, 20 Juans.

See?

Is this a good length, or should

it be shorter?

I think it looks really good.

I'm still concerned about the

stability.

Ana, can you hold the chassis

down?

Yeah.

I think that's going to help

a lot.

Yeah, good job.

Right now I am gathering

stuff to make a drag plate.

That looks awesome.

So when it's being stepped

on, the bungee is stretched.

Uh-huh.

But when it's not being

stepped on, it'll be held up.

That's great.

Think you'll be able to do that

in, like, an hour?

Yeah.

It should be a really quick

thing.

All right.

Okay, guys, let's see if we

can finish this quickly.

The brake's done.

Guys, this is awesome.

Okay, let's go test.

Brake.

Good, good.

Brake, brake.

Perfect.

We're going to Jamaica.

Jamaica, Jamaica!

We're done.

It looks good.

We're ready to go.

All right, guys, it's done.

Yeah, let's try it.

Put your tools down and your

sandals on!

We're going to Jamaica!

Purple Team.

Nice job, guys.

This is really cool.

Jamaica, here we come.

I feel proud of what we made.

I really think it'll feel like

you're going on snow, because we

have the handlebars that go side

to side, and the weight shifting

that'll impact your turning.

So I feel like we really worekd

hard to integrate the snow

feeling into our sled.

I think we're going to do

really well.

I mean, I saw the Purple Team's

build, and it's really nice, but

I think our main selling point

is that it's light, and it'll be

a lot easier to glide on the

grass, and that's what they're

looking for.

We're all at the airport.

Where are we going?

Where are we going?

Jamaica!

Jamaica!

Jamaica!

We're so excited!

Land.

I see land.

Oh, look, it's the ocean!

Oh, goodness!

Look at the goats.

Oh, dude, it's a gaggle of

goats.

Jamaica.

Look, there's a fruit stand

right there.

Hey, guys, check out the

market on your left.

Come on down!

Welcome to Jamaica, friends,

and I hope you folks have a good

time.

Oh, look.

That's really good.

I can hear the ocean.

Do you want to hear the ocean?

Bob Marley.

[with Jamican accent] How you

doing, man?

Yeah.

I look cool, right?

You like it, you like it?

I can pull it off, dude.

I got the hips.

It's good, right?

It's good?

Here we are in Chukka Cove.

We're here!

I can't wait to meet the

dogs.

Do you speak Jamaican dog?

[barks], mon.

That's Jamaican dog.

The dog yards are right over

there in the corner.

Go, go, go!

I'm going, I'm going.

All right, guys, welcome to

Chukka Cove.

We have a little bit of time to

test the rigs before the clients

get here with the dogs.

Green Team, are you guys ready?

Yeah.

Yeah, let's go.

I would say take it all the

way up to the corner and make

that right turn, and you

probably want to test the brakes

too just to make sure they're

working okay.

Who's the dogs and who's the

musher?

I'm the musher, these are my

dogs.

Let's get ready to go.

In front?

Yeah, sure.

All right, you ready?

Yeah.

Don't go too fast.

You ready?

Don't go too fast?

Is this a race or is this a

stroll?

We're just testing it, Nate.

Okay, fine.

All right, fine.

On your mark, get set, go!

Wait, don't go that fast!

Not so fast!

Brake, brake, brake.

Try to brake it.

Try to brake it.

Ready?

It works.

You're right, it was really

You're right, it was really

good.

How was the stability?

It was stable, but it could

be a little bit more stable.

But it wasn't bad.

Did it go pretty well?

Yeah.

Looked like you made the turn

all right.

Yeah.

Brakes work?

Yes.

They do.

Sweet.

Ready for the dogs?

Yeah.

Purple Team's got to go

first, though.

All right, let's go test.

Starting line is right here.

All right, who are the dogs and

who's the musher?

Musher.

All right.

[dogs barking]

Okay, I'm sorry, I'm sorry.

I won't do it again.

Are you ready?

On your mark, get set, go!

Whoa!

Whoa.

You pulled me off of it.

Juan!

Oh, whoa!

Why was it going by itself?

Too much power!

Let's try that again.

I know how to tuck and roll,

but not crash a sled.

And Juan, try and keep the

pulling level low.

If it's up here, it's going to

pull it up too much.

All right, think like a dog,

Juan, but don't bark like one.

Ready, set, go!

Beautiful!

Look at all the grass I

dragged.

How'd it work?

It worked really well.

The handlebars steered, and this

drag plate, like, braked a lot.

Good.

Sweet.

So you guys ready to test with

the dogs?

Yeah.

Yeah, I think so.

Let's go meet the client.

Let's go.

Yeah, man.

She's so cute.

Isabella.

Hey, Jimmy.

You want a friend, too, huh?

Because we're using animals

from the pound, it shows how

much they care not just about

winning, but about the sport

itself and what it can stand

for.

So I really... I feel like

they'd be really great people to

meet, and I can't wait to show

them what we've made.

He doesn't like to be on

camera.

He's shy.

Hey, Design Squads, let's

huddle up.

Design Squads, I'd like you to

meet your client.

This is Rob and Newton.

Hey, guys.

Hi.

Hi, guys.

Have you meet all the dogs

already?

Yeah.

Are you guys ready to test

out the dog sleds?

Yeah.

Let's go do it.

This is going to be cool.

Yeah, we are.

All right, guys, here's the

plan.

We're going to run each sled

with a couple different

combinations of dogs.

We'll try two dogs and three

dogs just to see how they

perform.

Green Team's up first, and I

think Rob's going to drive.

Anything to prepare for?

The steering?

It's the opposite.

Okay.

Okay, and then braking, you

just put your foot down, and

it's like a bungee.

Okay.

Ready.

Ready?

Ready?

Let's go, let's go.

Hup, hup, hup, hup, hup.

Go, hup!

Hup, hup, up.

Go, Chukka, let's go.

Hup, hup, hup, hup.

Let's go.

Hup, hup, hup, hup.

Let's go.

Whoa, whoa.

Whoa.

The line snapped under the

wheel.

It feels good, but this could

be, like, somewhere up here.

Because as soon as the line gets

slack, it goes under the wheel,

and it picked up the rope.

Move it from up the front axle,

and maybe put it here.

The girl leads.

Let's go!

Go, go, go!

Yeah!

Hup, hup!

Let's go, Chukka, let's go!

Beautiful.

Hup, hup!

Hup, hup, hup!

Hup!

Go, go, go.

They're really fast.

Yeah, they are.

That's only three of them, too.

There they come.

All right.

Let's go check it out.

Yeah.

What'd you think of it?

Well, I think it went pretty

good using more dogs, so it's

less work on the guy.

It runs really smooth.

Because of the wheels, they are

so small, so it needed a little

bit more power to keep it going.

So it runs really smooth with

more dogs.

The steering went really good,

and the brake worked really

good, only that it's in a really

difficult position to reach to.

But other than that, it works

really well when you get to

reach it.

It is really light, but it's

really good for the dog, because

the lighter it is, the more

easier it is for the dogs to

pull.

So the lightness of it is

perfect also.

So good job, Green Team.

Thanks.

Yeah!

Nice work, guys.

Green Team!

Sweet.

Well, Purple Team, you ready to

run your dog sleds?

Yeah.

Let's go grab Newton and rig

it up.

Hold on, hold on, hold on,

hold on.

Okay, let's go!

Whoa, whoa, whoa, whoa!

Good dogs.

Good dogs.

Well, when I started out, and

the front went up, it's like a

wheelie.

It reminded me of the sled,

because you have to step on the

side to steer.

Okay, let's go.

Let's go, let's go.

Go, Newt!

Holy cow, look at him take

the corner.

So fast.

So fast.

They are hauling.

Go on, go on.

Go on, go on.

Here we go, come on!

Whoa, whoa, whoa.

Whoa, whoa.

How was it, Newton?

Yeah, man, it was fun in the

sun.

The turns were cool.

It was easy, very easy, but the

brakes is perfect.

It holds the dogs, and I think

it's one of the best things on

the rig here, man.

So does it feel like you're

snow dog sledding?

The steering is like you're

on snow.

Great.

Yeah.

It's really nice.

Well, Newton, let's go find

Rob and talk about which one is

actually better, and which

team's going to win.

All right.

All right, yeah.

Nice work, guys.

Thanks, Newton.

Yeah, man.

Thank you.

So what did you guys think of

the sleds?

Well, they were both two good

sleds.

To me they both feel nice,

comfortable.

Theirs did a lot better than

I thought it would.

I thought the Green Team's was

going to break as soon as he

hooked it up.

It doesn't look that strong.

It's not built out of steel.

But it did pretty well.

I think ours did pretty well.

I mean...

I think it was pretty light.

Yeah, it went fast.

He liked how it was lightweight

and everything.

And it wasn't going to break

because it had wooden dowels

inside, even though Annelise

said it would, but it wouldn't.

I don't know.

I think it can go either way.

It really could.

Yeah.

I was a little bit nervous,

though, because theirs were a

lot lighter, and it wouldn't

take much force to pull.

Theirs is just made out of

aluminum, but I don't even think

it is that much lighter, because

if you look at all the

reinforcing they had to do, I

mean, ours is the body and

that's it.

Like, no extra weight, no

superfluous pieces.

All that welding.

Yeah, it paid off in the end.

It's beautiful.

Whatever happens, you know,

at least we had fun.

Yeah.

So overall these feel a

little more like mushing on snow

than the existing carts that you

use for dry land?

As far as steering and...

Yeah, it has a little feel to

it as if you are riding in a

sled, because you have to lean

with the steering bar whenever

you are turning, and that's what

the sled is actually about.

For the Green Team, it was a

little less stabilized than the

Purple Team.

The Purple one, the brakes, I

love the brake system.

Yeah.

I love how it steered.

Yeah.

Here they come.

Well, well, well.

All right, Design Squads,

Newton and Rob have come to a

decision about the dog sleds.

Newton, you want to start?

Well, I think the Green Team

took the corner really good,

light for the dogs.

I think you guys did a really

good job.

Thanks.

Thank you.

The Purple Team sled, it was

a little bit more sturdier, and

it really feels as if it was...

we were riding an actual sled in

the snow.

So we would say Purple Team, you

are the winner.

Yeah!

Congratulations.

Nice job, Purple Team.




Congratulations.

All right, Green Team, nice

work.

I hope you've all had some fun

and learned some stuff.

I think this has been really

cool.

Yeah.

I'm so glad that the Purple

Team won, because we had a

really good teamwork going on.

We didn't think that we could do

it, and it was one of, like, the

proudest builds that I have,

like, made so far.

Wes is already in the final

anyway, so I don't feel so bad

that he lost.

But it's also great to even,

like, beat him.

Well, I mean, it was nice

winning four in a row.

It's a humbling experience to

finally lose one.

Jamaica's awesome.

I can't wait to jump off some

cliffs right now.

Welcome to Jamaica, man!

A win for Purple Team means that

Juan is tailing Wes by only 100

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.


Next time on Design Squad,

the teams get grilled.

I want you to build a

rotisserie.

Like a grandfather clock.

Some kind of water wheel.

That's some good pig.
