-It's StoryBots: Answer Time
-Answer Time!
5
00:00:20,875 --> 00:00:23,375
They live in your computer
And they've got a job to do
6
00:00:23,458 --> 00:00:25,750
They're all about learning
And they make it fun too
7
00:00:25,833 --> 00:00:28,166
-And when you have a question
-They'll answer it for you
8
00:00:28,250 --> 00:00:30,125
It's StoryBots: Answer Time
9
00:00:31,291 --> 00:00:32,375
Answer Time!
10
00:00:38,333 --> 00:00:40,416
-Hey, there!
-How's it going?
11
00:00:41,000 --> 00:00:44,500
Hi, Beep. How many muscles are there
in my body?
12
00:00:45,250 --> 00:00:49,291
Wow! There are over 600 muscles
in the human body.
13
00:00:49,375 --> 00:00:52,458
In fact, it takes over 40 of them
just to smile.
14
00:00:52,541 --> 00:00:53,916
Like this.
15
00:00:56,125 --> 00:00:58,666
Hi, Bo. Do you want to play hide and seek?
16
00:00:58,750 --> 00:01:01,000
Oh, I love hide and seek!
17
00:01:01,083 --> 00:01:03,291
One, two, three…
18
00:01:03,375 --> 00:01:04,625
We're starting!
19
00:01:05,125 --> 00:01:06,583
Four, five…
20
00:01:06,666 --> 00:01:07,791
Wait! No…
21
00:01:07,875 --> 00:01:09,583
Six, seven…
22
00:01:09,666 --> 00:01:12,083
-No. Over here!
-Eight, nine, ten.
23
00:01:12,166 --> 00:01:13,250
Goodness!
24
00:01:13,333 --> 00:01:16,000
Where are you hiding?
25
00:01:16,083 --> 00:01:17,916
Hi there!
26
00:01:19,541 --> 00:01:21,375
I found you.
27
00:01:21,458 --> 00:01:24,166
Oh, yes. You got me!
28
00:01:24,250 --> 00:01:27,250
Well, that was fun. But also stressful.
29
00:01:27,333 --> 00:01:28,208
Boop.
30
00:01:28,708 --> 00:01:32,333
Linguine, pepperoncini, courgette,
ham, Spam, clams…
31
00:01:32,416 --> 00:01:35,500
Whoa, Bang, you're on a roll
with those answers.
32
00:01:36,208 --> 00:01:38,708
Nah, I wasn't answering questions.
33
00:01:38,791 --> 00:01:41,125
I was just ordering a burrito.
34
00:01:42,333 --> 00:01:44,791
You put all that on a burrito?
35
00:01:44,875 --> 00:01:47,958
Yeah, man. Variety is the spice of life.
36
00:01:48,458 --> 00:01:49,416
Want a bite?
37
00:01:55,500 --> 00:01:57,833
We've got a Level Three coming in.
38
00:01:59,625 --> 00:02:03,083
Hey, StoryBots.
It's great to meet all of you.
39
00:02:03,166 --> 00:02:07,666
Holy… bananas!
40
00:02:07,750 --> 00:02:09,708
Are you seeing what I'm seeing?
41
00:02:09,791 --> 00:02:11,375
Boop!
42
00:02:11,875 --> 00:02:14,125
My name's Mr. Wonderful,
43
00:02:14,208 --> 00:02:18,500
and I have a little TV show called
Mr. Wonderful's Land of Imagination.
44
00:02:18,583 --> 00:02:22,041
Oh, we know who you are, Mr. Wonderful.
45
00:02:22,125 --> 00:02:24,625
You're, like, totally our idol and stuff.
46
00:02:24,708 --> 00:02:26,875
Yeah. We grew up watching your show!
47
00:02:26,958 --> 00:02:30,416
I've seen all 905 episodes! Twice!
48
00:02:31,416 --> 00:02:33,750
StoryBots, you all are so kind.
49
00:02:33,833 --> 00:02:37,208
I wish I could sit and chat
and get to know each of you,
50
00:02:37,291 --> 00:02:39,500
but I have a problem on my hands.
51
00:02:39,583 --> 00:02:42,916
We would do anything to help you,
Mr. Wonderful.
52
00:02:43,000 --> 00:02:45,000
Yeah, what can we do for you?
53
00:02:45,083 --> 00:02:49,416
It seems that the magical door knocker
to the Land of Imagination
54
00:02:50,000 --> 00:02:51,541
has fallen off.
55
00:02:52,666 --> 00:02:54,208
What?!
56
00:02:54,291 --> 00:02:56,500
If you can't use
the magical door knocker--
57
00:02:56,583 --> 00:02:59,083
You can't get into
the Land of Imagination!
58
00:02:59,166 --> 00:03:02,791
And millions of kids will be
totally disappointed and stuff!
59
00:03:03,708 --> 00:03:07,083
Yeah, we are in a little bit of a bind,
StoryBots.
60
00:03:07,166 --> 00:03:11,250
What? The door knocker
to the Land of Imagination has fallen off?
61
00:03:11,333 --> 00:03:14,583
The show starts in 17 minutes!
What are we gonna do?!
62
00:03:16,708 --> 00:03:21,541
As you can see, everyone around here
is a little upset. A little.
63
00:03:22,041 --> 00:03:25,791
You actually don't look that upset,
Mr. Wonderful.
64
00:03:26,375 --> 00:03:28,791
Yeah, you know, it's kinda my thing.
65
00:03:29,291 --> 00:03:31,791
Have you tried to glue
the door knocker back on?
66
00:03:31,875 --> 00:03:35,791
Actually, Bing, I did,
but the glue didn't work.
67
00:03:35,875 --> 00:03:37,791
Boop boop, boop, boop boop!
68
00:03:37,875 --> 00:03:40,958
Exactly, Boop.
If you can show me how glue works,
69
00:03:41,041 --> 00:03:43,208
then I can reattach the door knocker
70
00:03:43,291 --> 00:03:47,083
and get back to the Land of Imagination,
and we'll have our show.
71
00:03:47,166 --> 00:03:50,833
Hey, my friend Emmett is
super into making models,
72
00:03:50,916 --> 00:03:52,916
and he uses glue all the time.
73
00:03:53,000 --> 00:03:55,458
Maybe he can help us with how glue works.
74
00:03:55,541 --> 00:03:58,083
-Of course!
-Emmett could totally help!
75
00:03:58,166 --> 00:04:00,125
That's a really good idea, Bang.
76
00:04:00,208 --> 00:04:03,541
I love it. And I sure would appreciate
if you could help.
77
00:04:03,625 --> 00:04:05,791
There's only 15 minutes to showtime!
78
00:04:07,875 --> 00:04:09,083
And so would he.
79
00:04:09,583 --> 00:04:13,416
Don't worry, Mr. Wonderful.
We are on the job.
80
00:04:16,541 --> 00:04:17,500
Answer time!
81
00:04:18,708 --> 00:04:23,541
Hey, StoryBots. How will I know
what direction I'm going in?
82
00:04:25,083 --> 00:04:26,500
Do you feel lost?
83
00:04:28,083 --> 00:04:29,208
Directionless?
84
00:04:30,833 --> 00:04:34,041
Worried that you or a loved one
are unable to navigate?
85
00:04:34,125 --> 00:04:36,541
I'm telling you, I know where I'm going.
86
00:04:37,583 --> 00:04:39,416
Well, now there's hope.
87
00:04:39,500 --> 00:04:42,166
Now, there's cardinal directions.
88
00:04:42,250 --> 00:04:44,250
With four primary directions,
89
00:04:44,333 --> 00:04:47,291
north, south, east, and west,
90
00:04:47,375 --> 00:04:50,083
you'll be able to find
just about anything.
91
00:04:50,166 --> 00:04:52,833
There are many ways of guiding
your direction,
92
00:04:52,916 --> 00:04:56,541
such as a compass, the sun,
or even the stars in the sky.
93
00:04:56,625 --> 00:04:59,958
Full speed ahead, crew!
Follow the North Star!
94
00:05:01,583 --> 00:05:03,666
Once you've found your orientation,
95
00:05:03,750 --> 00:05:07,208
it's just a matter of knowing that
north is opposite south,
96
00:05:07,291 --> 00:05:09,916
that east is 90 degrees clockwise
from north,
97
00:05:10,000 --> 00:05:12,041
and that west is opposite east.
98
00:05:12,125 --> 00:05:16,291
Every time I wanted to watch the sunrise,
I'd look the wrong way.
99
00:05:16,791 --> 00:05:19,125
And watching the sunset was even worse!
100
00:05:21,166 --> 00:05:24,708
But now I know the sun rises in the east
and sets in the west,
101
00:05:24,791 --> 00:05:28,250
I haven't missed a single one.
Thanks, cardinal directions!
102
00:05:28,333 --> 00:05:31,791
Side effects of cardinal directions
include arriving on time,
103
00:05:31,875 --> 00:05:34,625
a stronger grasp of geography,
and understanding maps.
104
00:05:34,708 --> 00:05:37,625
Ask your cartographer
if cardinal directions are right for you.
105
00:05:37,708 --> 00:05:41,333
For those in search of more clarity,
try intercardinal directions.
106
00:05:41,416 --> 00:05:42,833
Use only as directed.
107
00:05:42,916 --> 00:05:44,916
We know the search can be long,
108
00:05:45,000 --> 00:05:47,750
but with cardinal directions,
there is a way.
109
00:05:49,000 --> 00:05:51,791
Maybe we should
ask someone for directions.
110
00:05:54,708 --> 00:05:57,625
Hey, StoryBots.
Can you please tell me a fun fact?
111
00:05:58,916 --> 00:06:01,625
Fun fact number 101.
112
00:06:03,208 --> 00:06:06,125
Did you know that snails
can take super long naps?
113
00:06:06,208 --> 00:06:08,708
Some have even slept
for up to three years!
114
00:06:09,458 --> 00:06:13,875
Okay, sleepy head.
It's been three years, time to wake up.
115
00:06:15,166 --> 00:06:16,625
What time is it?
116
00:06:16,708 --> 00:06:17,666
November.
117
00:06:19,125 --> 00:06:21,541
Just five more months, please.
118
00:06:21,625 --> 00:06:22,583
Okay, dear.
119
00:06:23,583 --> 00:06:25,125
Such a little angel.
120
00:06:33,916 --> 00:06:37,291
Next stop, Emmett's mum's house.
121
00:06:44,250 --> 00:06:47,000
Emmett? You, like, in here?
122
00:06:48,083 --> 00:06:51,583
Wow. This place is wild.
123
00:06:55,500 --> 00:06:57,750
And a "choo choo" to you too.
124
00:06:59,000 --> 00:07:00,500
-Hey, Bang!
-Whoa!
125
00:07:01,916 --> 00:07:04,583
Hey, Emmett. How you doing, man?
126
00:07:04,666 --> 00:07:09,333
Great, Bang. I just glued on
the last piece of my biggest model yet!
127
00:07:11,791 --> 00:07:14,208
Whoa. Awesome.
128
00:07:14,291 --> 00:07:16,250
But speaking of glue,
129
00:07:16,333 --> 00:07:20,083
I was hoping you could help me answer
a question for my friend--
130
00:07:20,583 --> 00:07:25,333
Emmett, honey, come upstairs for lunch.
Bang, you're welcome too, dear.
131
00:07:25,416 --> 00:07:27,875
Thanks, Mrs. Emmett's Mum,
132
00:07:27,958 --> 00:07:30,875
but I totally ate a burrito
before I got here.
133
00:07:30,958 --> 00:07:32,500
Be right there, Mum.
134
00:07:33,291 --> 00:07:37,791
Sorry, Bang, but Build Your Own Sandwich
Day waits for no man.
135
00:07:38,291 --> 00:07:40,791
Feel free to look around while I'm gone.
136
00:07:40,875 --> 00:07:44,250
Build Your Own Sandwich Day
Gotta build that sandwich
137
00:07:44,333 --> 00:07:48,000
Don't worry, Emmett.
Your stuff is safe with me, man.
138
00:07:48,708 --> 00:07:50,833
Huh? No way!
139
00:07:50,916 --> 00:07:54,750
A perfect scale replica
of the Space Blower-Upper 9000
140
00:07:54,833 --> 00:07:56,833
from SpaceBots in Outer Space?
141
00:07:56,916 --> 00:08:02,875
Man, this is, like, the most totally rare,
one-of-a-kind model I've ever seen.
142
00:08:02,958 --> 00:08:05,416
Better be super careful around this one--
143
00:08:06,041 --> 00:08:07,083
Huh?
144
00:08:19,375 --> 00:08:20,208
Huh?
145
00:08:30,958 --> 00:08:33,791
And one more slice of bread
ought to do it.
146
00:08:33,875 --> 00:08:37,375
Hurry and eat, Emmett.
You don't want to leave Bang waiting.
147
00:08:37,875 --> 00:08:42,000
Bang's the chillest guy I know.
What could possibly go wrong?
148
00:08:55,916 --> 00:08:57,083
Hey, what's up?
149
00:09:09,041 --> 00:09:11,083
Phew. That wasn't so bad.
150
00:09:26,333 --> 00:09:27,916
Hey, Bang, are you--
151
00:09:31,166 --> 00:09:34,000
Hi, StoryBots, my name is Finley.
152
00:09:34,666 --> 00:09:36,416
How deep is the ocean?
153
00:09:38,166 --> 00:09:40,500
-Hey, Dink?
Yeah, Doink?
154
00:09:41,000 --> 00:09:43,333
How deep do you think the ocean is?
155
00:09:44,500 --> 00:09:46,125
Wait, 100 feet?
156
00:09:47,041 --> 00:09:50,083
100 feet? It's gotta be
way more than that, like--
157
00:09:50,166 --> 00:09:52,166
Like 103 feet!
158
00:09:52,250 --> 00:09:56,750
Wait. You think it's three whole feet
more than 100?
159
00:09:56,833 --> 00:09:57,875
At least!
160
00:09:57,958 --> 00:10:01,375
Oh, yeah? Who told you that? A zebra?
161
00:10:01,458 --> 00:10:04,958
A zebra? That's funny.
You're a real comedian, aren't you?
162
00:10:05,041 --> 00:10:06,916
Yeah, and I got a joke for you.
163
00:10:07,000 --> 00:10:10,541
I know a guy who thinks the ocean
is 103 feet deep!
164
00:10:11,791 --> 00:10:14,958
That's it! I cannot be friends
with someone who thinks
165
00:10:15,041 --> 00:10:17,250
the ocean is less than 103 feet deep.
166
00:10:17,333 --> 00:10:20,625
Oh, yeah? I won't be friends
with you either then, okay?
167
00:10:20,708 --> 00:10:22,625
-Fine. Okay, fine.
-Fine.
168
00:10:22,708 --> 00:10:24,958
-Fine!
-Fine!
169
00:10:26,750 --> 00:10:29,916
Pardon me, but I couldn't help
overhear your argument
170
00:10:30,000 --> 00:10:32,083
and thought I could settle matters.
171
00:10:32,625 --> 00:10:36,958
The deepest part of the ocean
is 36,200 feet,
172
00:10:37,041 --> 00:10:39,250
or almost seven miles.
173
00:10:44,916 --> 00:10:47,916
Yeah, right, buddy,
and I'm the King of England!
174
00:10:49,166 --> 00:10:51,166
36,000 feet?
175
00:10:52,708 --> 00:10:56,708
Can you believe that shark thinks
he knows how deep the ocean is?
176
00:10:57,375 --> 00:10:59,750
What would a shark know about the ocean?
177
00:11:07,708 --> 00:11:10,916
We're diving down, down, down, down
And then we'll dive some more
178
00:11:11,000 --> 00:11:13,500
In the big deep ocean
That we love to explore
179
00:11:13,583 --> 00:11:16,666
We're dropping low, low, low, low
Because we're going to go
180
00:11:16,750 --> 00:11:19,416
To the deepest known point
On the ocean floor
181
00:11:19,500 --> 00:11:22,583
Under the waves, there are valleys
And hills all around
182
00:11:22,666 --> 00:11:25,666
On the average
It's about 12,000 feet down
183
00:11:25,750 --> 00:11:28,500
That's over 1,000 school buses
All in a stack
184
00:11:28,583 --> 00:11:30,500
Or 800 T-Rexes
185
00:11:30,583 --> 00:11:31,750
What a fun fact!
186
00:11:31,833 --> 00:11:34,958
But there's a way, way, way, way
Deeper place we know
187
00:11:35,041 --> 00:11:37,625
The Mariana Trench
Is where we've got to go
188
00:11:37,708 --> 00:11:40,875
Where the lowest known point
Is called Challenger Deep
189
00:11:40,958 --> 00:11:43,500
As low as 36,200 feet
190
00:11:43,583 --> 00:11:46,708
That's 20 tall skyscrapers
Under the sea
191
00:11:46,791 --> 00:11:49,625
Or 118 Statues of Liberty
192
00:11:49,708 --> 00:11:52,500
If you could sink Mount Everest
Down that deep
193
00:11:52,583 --> 00:11:55,458
There'd be a whole mile of water
Up over its peak
194
00:11:55,541 --> 00:11:58,541
We're dropping down, down, down, down
And then we'll drop some more
195
00:11:58,625 --> 00:12:01,625
Where hardly anyone has ever gone before
196
00:12:01,708 --> 00:12:04,750
We've got to dive, dive, dive
Till finally we arrive
197
00:12:04,833 --> 00:12:07,708
At the lowest known point
On the ocean floor
198
00:12:07,791 --> 00:12:11,583
Nearly seven miles down
On the ocean floor
199
00:12:14,250 --> 00:12:17,541
Next stop, Emmett's mum's house.
200
00:12:20,375 --> 00:12:22,916
Emmett, dude, I am so sorry.
201
00:12:23,000 --> 00:12:27,416
I am totally gonna fix all these models,
starting with this ship.
202
00:12:29,583 --> 00:12:34,125
Oh. Well, at least I saved
the Space Blower-Upper 9000?
203
00:12:36,166 --> 00:12:38,541
They're-- They're all broken.
204
00:12:39,291 --> 00:12:41,333
This… is…
205
00:12:42,083 --> 00:12:43,708
amazing!
206
00:12:44,291 --> 00:12:45,875
Uh, come again?
207
00:12:46,750 --> 00:12:51,333
Think of how much fun it'll be
putting all these models back together!
208
00:12:51,416 --> 00:12:53,583
Oh, man, that is such a relief.
209
00:12:53,666 --> 00:12:56,500
I thought you were going to
totally freak out.
210
00:12:56,583 --> 00:12:58,750
So, while we're fixing stuff,
211
00:12:58,833 --> 00:13:02,041
could you tell me
how glue works for Mr. Wonderful?
212
00:13:02,625 --> 00:13:04,833
Well, you've come to the right place.
213
00:13:04,916 --> 00:13:07,666
I know all sorts of ways glue works.
214
00:13:07,750 --> 00:13:11,750
In fact, I can show you
two main ways that glue works.
215
00:13:12,458 --> 00:13:15,791
The first is called mechanical locking.
216
00:13:16,375 --> 00:13:19,041
Mechanical locking, huh?
How does that work?
217
00:13:19,625 --> 00:13:20,625
Just listen.
218
00:13:21,541 --> 00:13:24,750
When you use a gob of glue
Just what exactly does it do
219
00:13:24,833 --> 00:13:28,083
To get things sticking?
220
00:13:28,166 --> 00:13:31,291
It can fix a flower pot
Or any broken toy you've got
221
00:13:31,375 --> 00:13:33,416
But how?
222
00:13:34,875 --> 00:13:38,000
If you magnify the smoothest stuff
223
00:13:38,083 --> 00:13:41,000
It's coarse and rough, you'll see
224
00:13:41,541 --> 00:13:44,541
Cracks and dents are many
Yes, there are plenty
225
00:13:44,625 --> 00:13:48,083
Here and there, everywhere
Roughness is the key
226
00:13:48,166 --> 00:13:51,333
Glue goes into tiny cracks
It oozes into all the gaps
227
00:13:51,416 --> 00:13:54,666
And there it hardens
228
00:13:54,750 --> 00:13:58,125
Everywhere that it can drip
It gets a firm and hearty grip
229
00:13:58,208 --> 00:14:01,416
And so
230
00:14:01,500 --> 00:14:08,000
When it dries completely
Then its grip is good and strong
231
00:14:08,083 --> 00:14:10,333
There you go, good as new
Through and through
232
00:14:10,416 --> 00:14:13,083
'Cause the glue won't let go
233
00:14:13,666 --> 00:14:15,291
That's mechanical locking.
234
00:14:15,375 --> 00:14:18,083
But glue also works on a molecular level.
235
00:14:18,166 --> 00:14:21,416
Atoms make up everything
That's the rule
236
00:14:21,500 --> 00:14:23,958
Though they're tiny, not very large
237
00:14:24,041 --> 00:14:27,708
And they combine into clusters
Called molecules
238
00:14:27,791 --> 00:14:31,458
Which often can have an electric charge
239
00:14:31,541 --> 00:14:34,791
Those have a couple of different ends
240
00:14:34,875 --> 00:14:37,708
Positive and negative too
241
00:14:37,791 --> 00:14:41,416
And when opposing ends line up
They stick to each other
242
00:14:41,500 --> 00:14:44,583
Like pairs of magnets do
It's true!
243
00:14:45,083 --> 00:14:48,000
There's a name for that.
Van der Waals forces.
244
00:14:48,083 --> 00:14:51,250
Now the molecules of glue
Are clinging by the millions
245
00:14:51,333 --> 00:14:54,625
To the things you're joining
246
00:14:54,708 --> 00:15:00,291
-So it helps them stick together
-That's the coolest thing I've ever seen
247
00:15:01,458 --> 00:15:04,375
Glue can work in many ways
248
00:15:04,458 --> 00:15:08,291
I've shown you only two
249
00:15:08,375 --> 00:15:09,208
Glue!
250
00:15:09,291 --> 00:15:12,791
But when you build a model truck
Or fix a handle on a cup
251
00:15:12,875 --> 00:15:16,416
Just think of all the great things
252
00:15:16,500 --> 00:15:21,750
Glue can do
253
00:15:25,000 --> 00:15:26,708
Whoa!
254
00:15:26,791 --> 00:15:29,250
Man, Emmett, you sure know your glue.
255
00:15:29,333 --> 00:15:32,625
Well, better give Mr. Wonderful
his answer. Thanks, man!
256
00:15:32,708 --> 00:15:34,583
No problem, Bang. Any time.
257
00:15:35,083 --> 00:15:37,083
Take care, brother. See ya. Bye!
258
00:15:37,166 --> 00:15:39,500
See you later! Take care! Goodbye!
259
00:15:43,958 --> 00:15:48,083
Oh, dear, it's broken.
Guess I gotta fix it again.
260
00:15:52,958 --> 00:15:55,625
Welcome, class.
There are two primary theories
261
00:15:55,708 --> 00:15:58,333
that explain how glue
sticks things together,
262
00:15:58,416 --> 00:16:01,500
which my assistant, Gopher,
will help me demonstrate.
263
00:16:02,333 --> 00:16:05,000
The first theory is called
mechanical locking.
264
00:16:05,083 --> 00:16:07,708
Even the smoothest-looking surfaces
are rough
265
00:16:07,791 --> 00:16:10,041
when you put them under a microscope.
266
00:16:10,125 --> 00:16:15,166
Mechanical locking happens when wet glue
pours into all of the small crevices
267
00:16:15,250 --> 00:16:16,250
and dries.
268
00:16:17,125 --> 00:16:21,458
It grips the microscopic rough surfaces
and holds them together.
269
00:16:24,083 --> 00:16:26,958
The second theory is called
van der Waals forces.
270
00:16:27,041 --> 00:16:31,250
It claims that things stick together
at the molecular level.
271
00:16:33,125 --> 00:16:35,458
Molecules are groups of atoms.
272
00:16:37,583 --> 00:16:42,000
Some of them have positive charges,
and some of them have negative charges.
273
00:16:42,833 --> 00:16:45,041
When molecules with positive charges
274
00:16:45,125 --> 00:16:49,125
and molecules with negative charges
line up, they stick together.
275
00:16:51,375 --> 00:16:54,875
Similar to the way opposite ends
of a magnet stick together.
276
00:16:56,625 --> 00:16:59,625
While van der Waals forces
and mechanical locking
277
00:16:59,708 --> 00:17:03,333
are the primary ways
that glue makes things stick together,
278
00:17:03,416 --> 00:17:06,833
people are still learning about
how glue works,
279
00:17:07,333 --> 00:17:10,541
and inventing new ways
to make better glues.
280
00:17:10,625 --> 00:17:12,333
Isn't that right, Gopher?
281
00:17:13,125 --> 00:17:14,125
A monster!
282
00:17:14,750 --> 00:17:16,041
Class dismissed!
283
00:17:16,583 --> 00:17:18,291
Run for your life!
284
00:17:25,083 --> 00:17:29,166
Hello? Mr. Wonderful? Are you there?
285
00:17:29,250 --> 00:17:31,583
Bang, I'm so glad you're back.
286
00:17:31,666 --> 00:17:35,166
Did you figure out how glue works
so I can get the knocker on the door?
287
00:17:35,250 --> 00:17:37,208
My friends are getting a little antsy.
288
00:17:37,291 --> 00:17:40,833
It's only one minute till showtime!
We're doomed!
289
00:17:40,916 --> 00:17:42,583
I sure did, Mr. Wonderful.
290
00:17:42,666 --> 00:17:46,666
But first, can you tell me
what the surface of your door feels like?
291
00:17:46,750 --> 00:17:49,375
Why, Bang, it's incredibly smooth.
292
00:17:49,458 --> 00:17:50,708
Like my bald head.
293
00:17:51,208 --> 00:17:55,333
Therein lies the problem, dude.
It's too smooth.
294
00:17:55,416 --> 00:17:58,000
Do you happen to have
any sandpaper nearby?
295
00:17:58,083 --> 00:18:00,750
You know what? I do have some sandpaper.
296
00:18:01,250 --> 00:18:02,458
Right here.
297
00:18:02,541 --> 00:18:06,416
Sweet! Now all you've got to do is
sand down the part of the door
298
00:18:06,500 --> 00:18:08,125
that the knocker sticks to.
299
00:18:12,583 --> 00:18:16,375
Bang, why are we using sandpaper
to make the smooth door rough?
300
00:18:16,458 --> 00:18:20,333
It creates grooves and crevices
that the glue can sink into.
301
00:18:20,416 --> 00:18:24,791
Then when it dries, it'll, like,
totally hold the knocker in place.
302
00:18:24,875 --> 00:18:27,708
That's called mechanical locking.
303
00:18:27,791 --> 00:18:30,375
Wow. Sounds very complicated.
304
00:18:30,916 --> 00:18:35,083
That's nothing, man. You should
hear about van der Waals forces.
305
00:18:36,500 --> 00:18:37,458
Done!
306
00:18:37,541 --> 00:18:42,166
All right. Now try re-gluing
that knocker back on.
307
00:18:46,250 --> 00:18:50,875
Look at that. With the rougher surface,
the glue stuck the knocker to the door.
308
00:18:50,958 --> 00:18:53,500
Mechanical locking for the win.
309
00:18:54,041 --> 00:18:58,791
Bang, thank you so much for all your help.
I wish I could stay and chat, but--
310
00:18:58,875 --> 00:19:01,083
There's only ten seconds to showtime!
311
00:19:01,833 --> 00:19:04,416
But it looks like
my show's about to start.
312
00:19:04,500 --> 00:19:07,000
It's our pleasure, Mr. Wonderful, dude.
313
00:19:07,083 --> 00:19:09,500
-Glad we could help!
-Good luck!
314
00:19:09,583 --> 00:19:11,833
Thank you all, StoryBots.
315
00:19:11,916 --> 00:19:15,208
I love you, and I'll see you
in the Land of Imagination.
