0:00:02 > 0:00:04- Hello, I'm Bitz. - And I'm Bob.
0:00:05 > 0:00:07- BOTH:- We love make-and-do.
0:00:07 > 0:00:10And with a little bit of know-how...
0:00:10 > 0:00:11You can do it, too!
0:00:11 > 0:00:12Let's go!
0:00:12 > 0:00:15# We can work it out
0:00:16 > 0:00:18# Whoa-oh
0:00:18 > 0:00:19# Ah-ah-ah-ah-ah
0:00:19 > 0:00:22# We can work it out
0:00:22 > 0:00:25# And we'll invent our way
0:00:25 > 0:00:29# Through ideas and play
0:00:29 > 0:00:31- # Bitz and Bob! - Will save the day. #
0:00:33 > 0:00:35Do you remember how we used
0:00:35 > 0:00:41engineering to get your go-kart go-go-going in the Wheelie Day race?
0:00:41 > 0:00:44- Um...can we check that, Bitz? - HE LAUGHS
0:00:46 > 0:00:47Go!
0:00:48 > 0:00:52Bob's go-kart didn't have a checklist to make it race-ready,
0:00:52 > 0:00:56and it soon turned into a no-go-kart.
0:00:56 > 0:01:00You did tighten all the bolts, didn't you?
0:01:00 > 0:01:02Uh...yes?
0:01:03 > 0:01:05Um, maybe I missed that one.
0:01:05 > 0:01:09It's time for a Bitz brain blitz!
0:01:10 > 0:01:14Bob didn't check all of his bolts before the race started
0:01:14 > 0:01:17and his go-kart came apart.
0:01:17 > 0:01:20If I make a checklist for Bob's
0:01:20 > 0:01:25go-kart, then we can use it to make sure nothing gets missed.
0:01:25 > 0:01:28Now, it's your turn to try.
0:01:28 > 0:01:32Look - she's making paper aeroplanes.
0:01:33 > 0:01:38They all look quite different.
0:01:38 > 0:01:40But our friend's on hand with a checklist.
0:01:40 > 0:01:43He's checking for two important details
0:01:43 > 0:01:46that help a paper aeroplane fly well -
0:01:46 > 0:01:48a pointy nose and level wings.
0:01:48 > 0:01:51If they get a cross, the plane is
0:01:51 > 0:01:55missing something important and needs fixing.
0:01:57 > 0:02:00When there's a tick, it's good to go.
0:02:00 > 0:02:05Now they've all passed the checklist, time for takeoff!
0:02:07 > 0:02:09Oh, yeah! Awesome!
0:02:09 > 0:02:13A checklist got my go-kart going, too.
0:02:14 > 0:02:16- Tick.- Right.
0:02:21 > 0:02:22BOB GRUNTS
0:02:22 > 0:02:25- Ah! And...- BOTH:- Tick!
0:02:26 > 0:02:27Ah. Perfect.
0:02:27 > 0:02:30- Yes! - THEY LAUGH
0:02:30 > 0:02:33Now, we're going to race balloon cars
0:02:33 > 0:02:36but use our checklist to make sure they're built correctly.
0:02:36 > 0:02:38Let's race! Go!
0:02:40 > 0:02:44Whoops! That didn't go well.
0:02:44 > 0:02:47You're right! Their cars aren't working.
0:02:47 > 0:02:51Let's get them back to the garage and check them over.
0:02:51 > 0:02:54How will they know what's wrong with them?
0:02:54 > 0:02:56Well, both teams have a checklist.
0:02:56 > 0:03:01They're checking each part of their car using their list.
0:03:02 > 0:03:05Balloon...check.
0:03:05 > 0:03:09Wheel...check... Oh, hang on a minute - there's no wheel.
0:03:09 > 0:03:14They followed the checklist, and now they can fix their car.
0:03:19 > 0:03:21Wheel...check.
0:03:21 > 0:03:25Tape...check... Ah! Look, Bitz -
0:03:25 > 0:03:27the tape's not in place.
0:03:27 > 0:03:32Now, they'll know how to fix their car, too!
0:03:32 > 0:03:35- Looking good! BOTH:- Woohoo!
0:03:35 > 0:03:37Let's race! Go!
0:03:38 > 0:03:43Ooh, yeah! Let's see it again.
0:03:46 > 0:03:48What a race!
0:03:48 > 0:03:51And it's all down to checking those checklists.
0:03:52 > 0:03:54That's it! Steam-pink style!
0:03:54 > 0:03:59Keep engineering and inventing your way to save the day!
0:03:59 > 0:04:01You can do it, too!
