Hello, I'm Bitz!

0:00:020:00:03

And I'm Bob!

0:00:030:00:05

-BOTH:

-We love make and do!

0:00:050:00:07

And with a little bit of know-how...

0:00:070:00:10

You can do it, too!

0:00:100:00:11

Let's go!

0:00:110:00:12

# We can work it out

0:00:120:00:17

# Whoa, whoa, whoa

0:00:170:00:19

# Ah, ah, ah

0:00:190:00:20

# We can work it out

0:00:200:00:23

# We'll invent a way

0:00:230:00:26

# Through ideas and play... #

0:00:260:00:28

-Bitz and Bob!

-# Will save the day. #

0:00:280:00:31

Bitz and Bob, Bitz and Bob, Bitz and Bob!

0:00:310:00:34

Do you remember what happened with the Desert Ranger 3000, Bob?

0:00:340:00:38

Yeah! We added stuff to make it the Desert Ranger 4000.

0:00:380:00:42

We over-engineered our vehicle.

0:00:440:00:47

-Hey, hey!

-We added wings, a hammock and a slide.

0:00:470:00:50

But then it didn't work properly for what we needed it to do.

0:00:500:00:54

Ah!

0:00:540:00:55

-Oh, no!

-We're stuck!

0:00:550:00:57

Ah! The slide's been dragging along the road.

0:00:590:01:03

Lots of things are engineered for a special purpose.

0:01:040:01:08

To go over bumpy surfaces, this car has big chunky wheels

0:01:080:01:12

and its body is high off the ground.

0:01:120:01:15

Or to go really fast, racing cars have smooth low bodies

0:01:150:01:19

with super grippy tyres to give them a good push.

0:01:190:01:23

Brrrrum, brrum, brrumm!

0:01:230:01:24

Now it's your turn to try.

0:01:240:01:26

Woohoo!

0:01:260:01:28

Oh, look.

0:01:290:01:30

They've got loads of things

0:01:300:01:32

they can use to make a car with.

0:01:320:01:35

And they're designing their cars to get down this track.

0:01:350:01:40

Look at this car. It has a double layer on it.

0:01:410:01:44

Wow, that's so cool!

0:01:450:01:47

They're putting wings on theirs.

0:01:470:01:49

Oh, yeah! And they're off!

0:01:520:01:55

Oh, no! Their cool car is too big.

0:01:550:01:59

Whoops! They can try again!

0:01:590:02:02

Here's the next team.

0:02:040:02:06

You can do it!

0:02:080:02:10

Oh, nearly!

0:02:100:02:13

It's a bit too tall.

0:02:130:02:14

Although their cars look so great, they've been over-engineered

0:02:140:02:18

with too much stuff and they can't get down the track.

0:02:180:02:22

That's just like what happened with our Desert Ranger 4000.

0:02:220:02:27

It's time for a Bitz Brain Blitz!

0:02:270:02:29

First, the slide was dragging along the road, slowing us down

0:02:310:02:35

and making the ride bumpy.

0:02:350:02:38

And now we can't drive up this hill because it's still too heavy

0:02:380:02:42

with all the extras we added to it.

0:02:420:02:44

We over-engineered it.

0:02:440:02:46

Come on, let's get rid of everything we don't need!

0:02:480:02:51

I want to use it for exactly what it was designed for

0:02:510:02:54

and that means losing the extra bits that were slowing us down.

0:02:540:02:58

# We're on our way to the big cactus... #

0:02:580:03:00

We're moving much faster now!

0:03:000:03:03

They're re-engineering theirs.

0:03:030:03:05

Cool! Let's see if it's fit for the job, Bob.

0:03:050:03:09

Go!

0:03:090:03:11

Oh, it's still too tall

0:03:110:03:13

to get under the low bridge.

0:03:130:03:15

You're going to have to take off more.

0:03:180:03:21

Aw!

0:03:210:03:22

There's no more double-decker,

0:03:220:03:25

but maybe this car's fit for purpose now

0:03:250:03:27

and can get down the track.

0:03:270:03:29

Let's go!

0:03:290:03:30

Yay!

0:03:320:03:34

Oh, yeah! Let's see it again.

0:03:340:03:36

Yay!

0:03:440:03:46

Awesome!

0:03:460:03:48

That's it!

0:03:480:03:49

Steam pink style!

0:03:490:03:51

Keep engineering and inventing away to save the day!

0:03:510:03:55

-BOTH:

-You can do it, too!

0:03:550:03:57

We're designing plastic-bottle cars to put to the test on our obstacle course. But can over-engineering stop the cars getting around the track? A simple re-engineer could solve the problem so the cars are fit for purpose.
