00:00:50,275 --> 00:00:53,827
Narrator: liquid medication
Used to always come in a bottle,
4
00:00:53,827 --> 00:00:56,724
And you had to pour
Your dose with a steady hand
5
00:00:56,724 --> 00:00:58,275
Into a spoon.
6
00:00:58,275 --> 00:01:01,034
Today, many medications
And supplements
7
00:01:01,034 --> 00:01:03,586
Come inside
Small food-safe casings
8
00:01:03,586 --> 00:01:06,379
That are easy to swallow
And portable --
9
00:01:06,379 --> 00:01:08,620
Soft gel capsules.
10
00:01:10,655 --> 00:01:13,758
Many types of products
Come in gel capsules,
11
00:01:13,758 --> 00:01:15,379
From prescription drugs
12
00:01:15,379 --> 00:01:18,172
To health supplements
Such as fish oils.
13
00:01:18,172 --> 00:01:21,896
Many of these medicine fills
Go bad if exposed to oxygen,
14
00:01:21,896 --> 00:01:24,724
So the gel cap,
Besides being convenient,
15
00:01:24,724 --> 00:01:27,241
Also serves
As a protective barrier.
16
00:01:27,241 --> 00:01:29,620
Every ingredient
In both the gel cap
17
00:01:29,620 --> 00:01:31,241
And the medicine fill inside
18
00:01:31,241 --> 00:01:34,000
Undergoes
Extensive testing for purity.
19
00:01:34,000 --> 00:01:38,310
The first test phase checks
For bacterial contamination.
20
00:01:38,310 --> 00:01:41,758
Lab technicians dissolve
The ingredients in solution,
21
00:01:41,758 --> 00:01:44,551
Apply it to a food source
In a petri dish,
22
00:01:44,551 --> 00:01:46,551
Then incubate
The dish for 72 hours
23
00:01:46,551 --> 00:01:49,620
To encourage
Any existing bacteria to grow.
24
00:01:49,620 --> 00:01:53,241
Then they draw samples and
Examine them under a microscope.
25
00:01:53,241 --> 00:01:55,620
If those samples
Are bacteria-free,
26
00:01:55,620 --> 00:01:59,103
The ingredient moves on
To the second phase of testing,
27
00:01:59,103 --> 00:02:02,241
Which checks for contaminants
Such as lead, arsenic,
28
00:02:02,241 --> 00:02:04,241
Mercury, and cadmium.
29
00:02:04,241 --> 00:02:06,965
This machine,
Called a spectrometer,
30
00:02:06,965 --> 00:02:10,275
Injects the ingredient solution
Into a plasma flame,
31
00:02:10,275 --> 00:02:13,862
Then, by reading the changes
In light wavelengths,
32
00:02:13,862 --> 00:02:15,931
Analyzes
The chemical composition.
33
00:02:15,931 --> 00:02:17,965
If the ingredient
Is contaminant-free,
34
00:02:17,965 --> 00:02:20,034
It gets the go-ahead.
35
00:02:20,034 --> 00:02:23,586
The gel cap is made entirely
Of natural ingredients --
36
00:02:23,586 --> 00:02:26,862
Gelatin derived
From beef bones,
37
00:02:26,862 --> 00:02:28,862
Palm oil glycerin,
38
00:02:28,862 --> 00:02:31,068
And purified water.
39
00:02:31,068 --> 00:02:33,344
The proportions are top-secret.
40
00:02:33,344 --> 00:02:37,206
An industrial blender combines
The three ingredients
41
00:02:37,206 --> 00:02:38,896
To a uniform consistency,
42
00:02:38,896 --> 00:02:42,241
Then heats the mixture
To 175 degrees fahrenheit.
43
00:02:42,241 --> 00:02:44,275
A vacuum sucks out
The air bubbles
44
00:02:44,275 --> 00:02:48,000
As this now-ready gel material
Flows into a holding tank.
45
00:02:48,000 --> 00:02:51,275
Simultaneously, they prepare
The medicine fill --
46
00:02:51,275 --> 00:02:54,241
In this case, vitamin d.
47
00:02:54,241 --> 00:02:56,241
They combine it with soybean oil
48
00:02:56,241 --> 00:02:59,000
To adjust the potency
To the specified strength.
49
00:02:59,000 --> 00:03:02,724
Meanwhile, they maintain
The gel-cap material
50
00:03:02,724 --> 00:03:05,965
In the holding tank
At 140 degrees fahrenheit
51
00:03:05,965 --> 00:03:08,413
To prevent it
From prematurely solidifying.
52
00:03:08,413 --> 00:03:11,551
Even the hose leaving that tank
Is wrapped in heater tape
53
00:03:11,551 --> 00:03:13,724
To keep the gel liquid.
54
00:03:13,724 --> 00:03:16,689
A separate hose feeds
The vitamin d solution
55
00:03:16,689 --> 00:03:18,137
From another holding tank
56
00:03:18,137 --> 00:03:20,241
Down to the production floor,
As well.
57
00:03:20,241 --> 00:03:22,724
This hose doesn't
Require heating
58
00:03:22,724 --> 00:03:27,793
Because vitamin d and soybean
Oil don't solidify when cool.
59
00:03:27,793 --> 00:03:30,620
On the production line,
Two stations simultaneously
60
00:03:30,620 --> 00:03:33,241
Spread a thin layer
Of molten gel
61
00:03:33,241 --> 00:03:34,724
Across a cooling drum.
62
00:03:34,724 --> 00:03:38,379
The gel hardens into
A solid, yet malleable, sheet
63
00:03:38,379 --> 00:03:40,482
About the thickness
Of cardboard.
64
00:03:40,482 --> 00:03:43,034
Each sheet passes over
A rotating die
65
00:03:43,034 --> 00:03:45,793
With capsule-shaped cavities.
66
00:03:45,793 --> 00:03:48,068
Just before the two gel sheets
Come together,
67
00:03:48,068 --> 00:03:50,379
Pumps inject
The required quantity
68
00:03:50,379 --> 00:03:53,517
Of vitamin d solution
Into each cavity,
69
00:03:53,517 --> 00:03:55,965
The pressure pushing
The gelatin into the cavity.
70
00:03:55,965 --> 00:03:59,172
At the same time,
The machine heats the gel sheets
71
00:03:59,172 --> 00:04:02,379
So that when they meet,
They adhere to each other,
72
00:04:02,379 --> 00:04:03,862
Forming full capsules
73
00:04:03,862 --> 00:04:06,689
With the vitamin d solution
Sealed inside.
74
00:04:06,689 --> 00:04:08,068
In the final second,
75
00:04:08,068 --> 00:04:11,241
The die's sharp edges slice
The gel caps free,
76
00:04:11,241 --> 00:04:13,655
And they fall
To a conveyer belt below.
77
00:04:13,655 --> 00:04:15,275
At this point,
78
00:04:15,275 --> 00:04:17,655
The filled gel caps contain
A fair bit of moisture,
79
00:04:17,655 --> 00:04:20,172
So they're quite soft.
80
00:04:20,172 --> 00:04:22,137
If they lay
On a surface too long,
81
00:04:22,137 --> 00:04:23,275
They'd flatten,
82
00:04:23,275 --> 00:04:25,344
So the conveyer belt whisks them
Very quickly
83
00:04:25,344 --> 00:04:27,034
Into a rotating drum,
84
00:04:27,034 --> 00:04:29,517
Where they tumble
In slightly cold, dry air
85
00:04:29,517 --> 00:04:31,793
For about three hours.
86
00:04:31,793 --> 00:04:35,172
This removes enough moisture
To make the gel caps hard enough
87
00:04:35,172 --> 00:04:37,931
To lie on a surface
Without flattening.
88
00:04:37,931 --> 00:04:42,551
After exiting, the gel caps move
Into a second dryer,
89
00:04:42,551 --> 00:04:44,586
Where,
Spread out on trays this time,
90
00:04:44,586 --> 00:04:47,482
They dry for about 36 hours.
91
00:04:47,482 --> 00:04:48,827
After that,
92
00:04:48,827 --> 00:04:51,965
The gel caps are hard enough
To be safely packaged.
93
00:04:51,965 --> 00:04:55,034
The gel caps --
94
00:04:55,034 --> 00:04:58,241
The ones being packaged here
Contain flax oil --
95
00:04:58,241 --> 00:05:00,517
Travel down a series
Of vibrating plates,
96
00:05:00,517 --> 00:05:03,827
Which progressively line them up
In single file.
97
00:05:03,827 --> 00:05:06,689
As they pass by,
98
00:05:06,689 --> 00:05:08,689
Electronic eyes count out
The number
99
00:05:08,689 --> 00:05:10,275
Of capsules per bottle,
100
00:05:10,275 --> 00:05:13,068
Triggering the filling mechanism
To collect that quantity
101
00:05:13,068 --> 00:05:15,862
And release it
Into an empty bottle.
102
00:05:23,379 --> 00:05:26,689
The next station applies
A plastic twist cap,
103
00:05:26,689 --> 00:05:28,793
Then the bottles move onward,
104
00:05:28,793 --> 00:05:31,586
Each one plowing
Directly into the center
105
00:05:31,586 --> 00:05:33,448
Of an adhesive-backed label,
106
00:05:33,448 --> 00:05:37,241
Which rollers then apply
Around he sides.
107
00:05:37,241 --> 00:05:38,448
Before shipping,
108
00:05:38,448 --> 00:05:41,206
The quality-control lab tests
Random samples
109
00:05:41,206 --> 00:05:42,655
From the production batch
110
00:05:42,655 --> 00:05:46,068
To verify that the gel caps
Meet all specifications.
111
00:05:57,827 --> 00:06:00,241
Narrator:
It's a playground staple --
112
00:06:00,241 --> 00:06:02,689
A stationary
Ride-on cartoon animal
113
00:06:02,689 --> 00:06:05,827
That bounces up and down
And rocks back and forth,
114
00:06:05,827 --> 00:06:08,172
Courtesy of
A huge spring underneath
115
00:06:08,172 --> 00:06:09,758
Secured into the ground.
116
00:06:09,758 --> 00:06:12,551
The bouncy coil base
Is what gives this type
117
00:06:12,551 --> 00:06:15,724
Of playground equipment
Its name -- a spring rider.
118
00:06:19,068 --> 00:06:22,758
The spring rider
Is a playground favorite.
119
00:06:22,758 --> 00:06:24,965
To withstand years
Of rambunctious riders,
120
00:06:24,965 --> 00:06:27,379
It has to be solid and durable,
121
00:06:27,379 --> 00:06:30,586
Yet for a toddler to be able
To rock back and forth,
122
00:06:30,586 --> 00:06:32,034
It can't be too heavy.
123
00:06:32,034 --> 00:06:34,931
That's why the spring is made
Of thick steel,
124
00:06:34,931 --> 00:06:37,517
And the animal
Of lightweight aluminum.
125
00:06:37,517 --> 00:06:42,137
That sand core
Is comprised of two halves,
126
00:06:42,137 --> 00:06:44,689
Each made
With an aluminum mold --
127
00:06:44,689 --> 00:06:46,517
Duck-shaped in this case.
128
00:06:46,517 --> 00:06:49,482
Workers fill it
With sand and adhesive mix
129
00:06:49,482 --> 00:06:51,448
That sets into a solid block.
130
00:06:51,448 --> 00:06:55,482
They insert
Several steel support rods,
131
00:06:55,482 --> 00:06:59,931
Fill to the top,
And even out the surface,
132
00:06:59,931 --> 00:07:02,793
Then expose two hooks
They'll later grab
133
00:07:02,793 --> 00:07:05,931
To extract the core half
Once the sand hardens
134
00:07:05,931 --> 00:07:07,517
In about 20 minutes.
135
00:07:07,517 --> 00:07:11,068
Meanwhile, other workers use
An aluminum pattern
136
00:07:11,068 --> 00:07:13,655
To make each half
Of the duck casting mold.
137
00:07:13,655 --> 00:07:16,793
After applying
A powder release agent
138
00:07:16,793 --> 00:07:18,517
To prevent sticking,
139
00:07:18,517 --> 00:07:20,379
They cover the pattern
140
00:07:20,379 --> 00:07:23,689
With a sieved mixture
Of sand and clay.
141
00:07:23,689 --> 00:07:26,344
They mount a frame
Around the pattern
142
00:07:26,344 --> 00:07:27,758
To contain the sand,
143
00:07:27,758 --> 00:07:29,482
As they add more and more,
144
00:07:29,482 --> 00:07:32,103
Repeatedly packing it down
In all areas
145
00:07:32,103 --> 00:07:35,827
With a pneumatic ramming tool.
146
00:07:35,827 --> 00:07:38,241
Then they remove the frame
147
00:07:38,241 --> 00:07:40,586
And cover the sand
With a wooden board.
148
00:07:40,586 --> 00:07:42,931
This provides
A hard surface for the press,
149
00:07:42,931 --> 00:07:47,000
Which now applies the weight
Of about four mid-sized s.U.V.S.
150
00:07:47,000 --> 00:07:49,137
Then they flip over the mold
151
00:07:49,137 --> 00:07:53,000
And remove the pattern
Which formed the mold cavity.
152
00:07:53,000 --> 00:07:55,379
The sand
Is now so firmly compacted
153
00:07:55,379 --> 00:07:57,482
That it holds the shape.
154
00:07:57,482 --> 00:08:00,689
One half of the sand mold
Has channels
155
00:08:00,689 --> 00:08:03,862
Through which the molten metal
Will flow into the cavity.
156
00:08:03,862 --> 00:08:07,896
Workers now position several
Quarter-inch-thick foam spacers
157
00:08:07,896 --> 00:08:08,965
In the cavity
158
00:08:08,965 --> 00:08:11,586
And place
Half of the core on top of them.
159
00:08:11,586 --> 00:08:13,689
The spacers elevate the core,
160
00:08:13,689 --> 00:08:17,517
Creating a quarter-inch cavity
Between core and mold.
161
00:08:17,517 --> 00:08:20,448
The other half of the core
Goes on top.
162
00:08:22,482 --> 00:08:25,068
After placing spacers
On top of that
163
00:08:25,068 --> 00:08:28,482
To create a quarter-inch gap
On this side, as well,
164
00:08:28,482 --> 00:08:32,000
They carefully lower
The other half of the sand mold.
165
00:08:32,000 --> 00:08:34,517
Now they're ready
To cast the duck.
166
00:08:34,517 --> 00:08:36,448
The melting point of aluminum
167
00:08:36,448 --> 00:08:39,517
Is just over
1,090 degrees fahrenheit.
168
00:08:39,517 --> 00:08:42,931
However, they heat much higher,
To 1,400 degrees,
169
00:08:42,931 --> 00:08:46,689
So it'll flow faster
And fill the entire cavity
170
00:08:46,689 --> 00:08:49,655
Before beginning to solidify.
171
00:08:49,655 --> 00:08:52,000
They pour the metal
Through holes on top.
172
00:08:52,000 --> 00:08:54,793
It flows through the runners
Into the mold cavity,
173
00:08:54,793 --> 00:08:56,482
Which is that quarter-inch gap
174
00:08:56,482 --> 00:08:58,482
Surrounding
The duck-shaped core.
175
00:08:58,482 --> 00:09:04,103
About 20 minutes later, the
Metal has cooled and solidified.
176
00:09:04,103 --> 00:09:07,344
They break the mold apart
On a vibrating sieve,
177
00:09:07,344 --> 00:09:10,551
Releasing the aluminum duck
And shaking out the core sand
178
00:09:10,551 --> 00:09:13,000
Through a hole
At the bottom of the duck.
179
00:09:13,000 --> 00:09:15,034
After cutting off
Excess aluminum
180
00:09:15,034 --> 00:09:16,655
That hardened in the runners,
181
00:09:16,655 --> 00:09:18,793
They grind down the seam,
182
00:09:18,793 --> 00:09:22,482
Which formed in between
The two halves of the mold.
183
00:09:22,482 --> 00:09:25,172
Next, they weld on
Aluminum handles
184
00:09:25,172 --> 00:09:27,862
For the child
To grip when riding.
185
00:09:27,862 --> 00:09:31,586
These handles are cast in
Sand molds just like the duck.
186
00:09:34,758 --> 00:09:37,275
Workers grind down
The weld and any sharp edges,
187
00:09:37,275 --> 00:09:43,206
Making the entire surface
Nice and smooth.
188
00:09:43,206 --> 00:09:46,620
Next --
A coat of polyester powder
189
00:09:46,620 --> 00:09:50,896
In bright rubber-ducky yellow.
190
00:09:50,896 --> 00:09:54,275
Then -- a 20-minute trip
Through an oven
191
00:09:54,275 --> 00:09:57,965
To bake the coating,
Making it ultra-durable.
192
00:09:57,965 --> 00:10:03,137
Now, delicately airbrushed
With the urethane enamel paint,
193
00:10:03,137 --> 00:10:06,034
The details
That bring mr. Duck to life --
194
00:10:06,034 --> 00:10:09,793
His feet, wings, bill, and eyes.
195
00:10:09,793 --> 00:10:14,103
The thick coil
That makes this a spring rider
196
00:10:14,103 --> 00:10:17,103
Is made
Of a flexible type of steel.
197
00:10:17,103 --> 00:10:20,310
They bolt
A steel spacer plate to it...
198
00:10:22,482 --> 00:10:25,448
...Then hide the bolts
Under an aluminum cover.
199
00:10:27,931 --> 00:10:31,793
After attaching a foot rest --
Steel, again --
200
00:10:31,793 --> 00:10:34,827
They bolt the duck to the plate.
201
00:10:34,827 --> 00:10:38,758
All these parts,
Like the duck, are painted
202
00:10:38,758 --> 00:10:41,620
With baked-on polyester coating.
203
00:10:41,620 --> 00:10:45,482
The spring bolts to a concrete
Block buried underground.
204
00:10:45,482 --> 00:10:48,448
Ducky and friends
Are designed to withstand
205
00:10:48,448 --> 00:10:50,241
Even the harshest winters,
206
00:10:50,241 --> 00:10:54,000
Letting children enjoy
A little spring all year round.
207
00:11:04,655 --> 00:11:09,103
Narrator: early versions of
Pancakes were thin like crepes.
208
00:11:09,103 --> 00:11:13,413
By the 1780s, american cooks
Were adding a leavening agent
209
00:11:13,413 --> 00:11:16,413
For a fluffier,
More filling pancake.
210
00:11:16,413 --> 00:11:19,931
That's when pancakes
Transitioned from side dish
211
00:11:19,931 --> 00:11:23,206
To main course
For the first meal of the day.
212
00:11:26,275 --> 00:11:31,379
Call them hot cakes, griddle
Cakes, flapjacks, or pancakes,
213
00:11:31,379 --> 00:11:34,517
There's nothing
Like a heaping helping of them
214
00:11:34,517 --> 00:11:35,896
Splashed with syrup.
215
00:11:35,896 --> 00:11:37,620
And with frozen pancakes,
216
00:11:37,620 --> 00:11:41,103
Whipping up some for breakfast
Has never been easier.
217
00:11:43,551 --> 00:11:47,000
Pancake production starts off
With a leavening agent --
218
00:11:47,000 --> 00:11:48,517
The baking powder.
219
00:11:48,517 --> 00:11:52,103
They combine salt, whey,
And various flavorings
220
00:11:52,103 --> 00:11:53,413
In a big blender
221
00:11:53,413 --> 00:11:56,000
To create
A dry-ingredient premix.
222
00:11:58,965 --> 00:12:01,689
Since these will be
Buttermilk pancakes,
223
00:12:01,689 --> 00:12:07,000
They add
Powdered buttermilk for flavor.
224
00:12:07,000 --> 00:12:10,275
They now pump liquid ingredients
From storage tanks
225
00:12:10,275 --> 00:12:11,758
Into a huge blender.
226
00:12:14,793 --> 00:12:17,586
These include water and eggs,
227
00:12:17,586 --> 00:12:20,586
Sweet cream, liquefied sugar,
228
00:12:20,586 --> 00:12:22,310
And soybean oil.
229
00:12:22,310 --> 00:12:24,862
They add
The dry premix and flour
230
00:12:24,862 --> 00:12:28,344
Until the batter reaches
The desired consistency.
231
00:12:28,344 --> 00:12:31,103
An employee tests
The batter's viscosity
232
00:12:31,103 --> 00:12:34,206
By pouring some
In a device with a little gate.
233
00:12:34,206 --> 00:12:38,172
He opens the gate and measures
The flow down a ramp.
234
00:12:38,172 --> 00:12:40,793
If it runs
Too thick or too thin,
235
00:12:40,793 --> 00:12:42,689
It won't produce pancakes
236
00:12:42,689 --> 00:12:45,620
That are the desired diameter
And uniformity.
237
00:12:45,620 --> 00:12:48,551
The pancake batter passes
The viscosity test.
238
00:12:48,551 --> 00:12:51,379
They release the batter
From the holding tank,
239
00:12:51,379 --> 00:12:53,965
And it flows
Into a depositor system.
240
00:12:56,793 --> 00:12:59,034
The depositor has nine nozzles.
241
00:12:59,034 --> 00:13:03,068
Each nozzle shoots an exact
Amount of the pancake batter
242
00:13:03,068 --> 00:13:07,379
Onto a hot moving griddle.
243
00:13:07,379 --> 00:13:09,241
Because of
The perfect viscosity,
244
00:13:09,241 --> 00:13:13,862
Each deposit of batter radiates
Out to form a neat, round shape,
245
00:13:13,862 --> 00:13:16,724
Each one the same size
As the next --
246
00:13:16,724 --> 00:13:20,551
About four inches in diameter.
247
00:13:20,551 --> 00:13:25,275
They run three depositors and
Moving griddles simultaneously
248
00:13:25,275 --> 00:13:28,137
To produce
750 pancakes a minute.
249
00:13:28,137 --> 00:13:32,206
That's an incredible
45,000 pancakes an hour.
250
00:13:35,172 --> 00:13:38,068
After several seconds
On the griddle,
251
00:13:38,068 --> 00:13:39,586
One side is cooked,
252
00:13:39,586 --> 00:13:44,827
So automated stainless-steel
Spatulas flip the pancakes over.
253
00:13:44,827 --> 00:13:47,551
There are two sets of flippers.
254
00:13:47,551 --> 00:13:50,793
After flipping,
The first set repositions,
255
00:13:50,793 --> 00:13:53,724
And the second set flips
The next row of pancakes.
256
00:13:53,724 --> 00:13:57,137
It's mechanized synchronization.
257
00:13:59,344 --> 00:14:03,482
The flippers are spaced apart
Exactly as the depositors are
258
00:14:03,482 --> 00:14:07,586
So the pancakes arrive at the
Flippers in the correct order
259
00:14:07,586 --> 00:14:09,793
To be picked up and turned over.
260
00:14:12,862 --> 00:14:14,206
Once flipped,
261
00:14:14,206 --> 00:14:16,689
The pancakes continue
Along the cooking conveyer,
262
00:14:16,689 --> 00:14:18,379
And the other side is cooked.
263
00:14:18,379 --> 00:14:23,413
It's a short ride
For these pancakes
264
00:14:23,413 --> 00:14:25,379
To be completely cooked.
265
00:14:29,241 --> 00:14:30,724
From dollops of batter
266
00:14:30,724 --> 00:14:33,448
To uniformly rounded
And cooked pancakes,
267
00:14:33,448 --> 00:14:36,965
This process has taken
Just 90 seconds.
268
00:14:36,965 --> 00:14:41,034
The pancakes somersault off
The cooking griddle
269
00:14:41,034 --> 00:14:44,344
And over a roller
To land on the next conveyer.
270
00:14:44,344 --> 00:14:48,724
The somersault exit
Has a purpose.
271
00:14:48,724 --> 00:14:54,482
It keeps the pancakes from
Folding over so they land flat.
272
00:14:54,482 --> 00:15:00,448
Hot off the griddles, the
Pancakes cool down on the ride,
273
00:15:00,448 --> 00:15:03,344
As all three production lines
Merge
274
00:15:03,344 --> 00:15:05,172
And head into a freezer.
275
00:15:09,793 --> 00:15:12,793
Inside the freezer,
276
00:15:12,793 --> 00:15:15,517
It's a very frigid
Minus-18 degrees,
277
00:15:15,517 --> 00:15:19,034
And the pancakes freeze fast.
278
00:15:19,034 --> 00:15:22,793
Now it's over
To the packaging line.
279
00:15:22,793 --> 00:15:26,206
This is where the uniformity
Of these pancakes pays off.
280
00:15:26,206 --> 00:15:30,068
Their similar diameter means
They can be neatly packed
281
00:15:30,068 --> 00:15:32,655
In groups of six.
282
00:15:36,655 --> 00:15:40,758
Machinery seals two stacks
Of six frozen pancakes
283
00:15:40,758 --> 00:15:45,172
In one wrapping.
284
00:15:45,172 --> 00:15:47,137
It has taken
Less than five minutes
285
00:15:47,137 --> 00:15:50,620
To prepare, freeze,
And package these pancakes.
286
00:15:50,620 --> 00:15:53,310
At home,
Prep time in the microwave
287
00:15:53,310 --> 00:15:55,068
Should be mere seconds.
288
00:15:55,068 --> 00:15:58,896
Just add syrup, and
This story has a sweet ending.
289
00:16:11,827 --> 00:16:15,689
Narrator:
Natural rubber comes from the
Milky sap of a tropical tree.
290
00:16:15,689 --> 00:16:17,068
Thousands of years ago,
291
00:16:17,068 --> 00:16:19,655
The native people
Of central and south america
292
00:16:19,655 --> 00:16:22,793
Discovered that the hardened sap
Was elastic and bounced.
293
00:16:22,793 --> 00:16:25,448
They played games
With the balls of sap.
294
00:16:25,448 --> 00:16:27,827
When european explorers
Came along,
295
00:16:27,827 --> 00:16:30,103
It was soon
A whole new ball game.
296
00:16:33,482 --> 00:16:36,482
Today, we make
Thousands of useful things
297
00:16:36,482 --> 00:16:40,241
From the fluid that circulates
Through rubber trees --
298
00:16:40,241 --> 00:16:43,379
Everything from tires
To balloons to boots.
299
00:16:43,379 --> 00:16:45,482
The seeds are sewn
On plantations
300
00:16:45,482 --> 00:16:47,000
Like this one in thailand.
301
00:16:49,103 --> 00:16:52,724
It takes several years
For the rubber trees to mature,
302
00:16:52,724 --> 00:16:55,241
Then the sap is ready to tap.
303
00:16:55,241 --> 00:16:59,379
In the coolness of the morning,
When the sap flows freely,
304
00:16:59,379 --> 00:17:04,310
The farm worker slashes
The bark with a hook blade.
305
00:17:04,310 --> 00:17:06,517
The sap oozes from the abrasion.
306
00:17:06,517 --> 00:17:09,034
It spills onto a metal spout
307
00:17:09,034 --> 00:17:11,896
Inserted
Below the slashed section.
308
00:17:11,896 --> 00:17:17,758
The spout funnels the sap
Into a ceramic cup below.
309
00:17:17,758 --> 00:17:20,517
It flows
For about five or six hours,
310
00:17:20,517 --> 00:17:22,448
Partially filling the cup.
311
00:17:22,448 --> 00:17:25,586
They wait a couple of days
For the tree to recover
312
00:17:25,586 --> 00:17:28,655
And then tap
Another section of the tree.
313
00:17:28,655 --> 00:17:32,689
After straining impurities,
314
00:17:32,689 --> 00:17:37,379
They pour the rubber sap
Into a plastic tub.
315
00:17:37,379 --> 00:17:42,034
They add formic acid
And swish it around.
316
00:17:42,034 --> 00:17:44,896
The acid causes
The sap to coagulate.
317
00:17:44,896 --> 00:17:48,206
After 15 to 30 minutes,
318
00:17:48,206 --> 00:17:53,896
It thickens
To the consistency of tofu.
319
00:17:53,896 --> 00:17:57,344
This tofu-like sap has
A sticky structure
320
00:17:57,344 --> 00:18:01,896
That allows it
To now be rolled out like dough.
321
00:18:01,896 --> 00:18:04,448
The rolling squeezes out
Excess water
322
00:18:04,448 --> 00:18:07,241
And leaves
A ribbed pattern on the sheets
323
00:18:07,241 --> 00:18:10,931
That increases the surface area
To hasten drying.
324
00:18:10,931 --> 00:18:14,965
Then they rinse off
The formic acid.
325
00:18:14,965 --> 00:18:19,862
They hang the rubber sheets
To dry for about five hours.
326
00:18:19,862 --> 00:18:23,931
As they dry, the rubber thickens
And becomes stronger,
327
00:18:23,931 --> 00:18:26,172
And the color darkens.
328
00:18:26,172 --> 00:18:30,000
The coagulated rubber sap
Has been transformed.
329
00:18:30,000 --> 00:18:34,482
In a few short steps, it's gone
From a liquid to a solid.
330
00:18:34,482 --> 00:18:37,620
Workers pile
The rubber sheets onto pallets
331
00:18:37,620 --> 00:18:41,034
And weigh the load.
332
00:18:41,034 --> 00:18:46,655
There's a little over a ton and
A half of rubber in this stack.
333
00:18:46,655 --> 00:18:49,206
They store
The stacks in a warehouse
334
00:18:49,206 --> 00:18:51,758
Until the next stage
Of processing.
335
00:18:51,758 --> 00:18:54,275
When they're ready to move on,
336
00:18:54,275 --> 00:18:57,103
Workers peel
Each sheet from the stack
337
00:18:57,103 --> 00:18:59,689
And soak them in water
For about 20 minutes.
338
00:18:59,689 --> 00:19:02,862
This washes away some
Of the surface contaminants,
339
00:19:02,862 --> 00:19:03,931
But not all.
340
00:19:06,793 --> 00:19:10,551
The rubber sheets then go
Into a machine with many brushes
341
00:19:10,551 --> 00:19:13,172
That scrub off more of the dirt.
342
00:19:15,413 --> 00:19:20,827
After one more rinse, the
Rubber sheets are squeaky-clean.
343
00:19:20,827 --> 00:19:25,379
As you can see, the color of
The rubber sheets vary somewhat
344
00:19:25,379 --> 00:19:28,103
Depending
On the tree they came from,
345
00:19:28,103 --> 00:19:30,241
Their thickness,
And other factors.
346
00:19:33,689 --> 00:19:36,793
They hang
The sheets on racks to drip dry.
347
00:19:42,034 --> 00:19:44,931
Next, they build
A fire in a brick oven
348
00:19:44,931 --> 00:19:47,310
And smoke the rubber sheets
In a chamber overhead
349
00:19:47,310 --> 00:19:50,103
For five days.
350
00:19:50,103 --> 00:19:53,034
It's a slow,
Low-temperature smoking
351
00:19:53,034 --> 00:19:57,275
That preserves the sheets
To prevent the growth of mold.
352
00:20:01,724 --> 00:20:04,724
After smoking,
They clip out contaminants
353
00:20:04,724 --> 00:20:08,344
Like bark or insects that have
Become imbedded in the rubber.
354
00:20:08,344 --> 00:20:12,000
In many cases,
They can't get it all.
355
00:20:12,000 --> 00:20:15,758
They grade the rubber sheets
By examining them
356
00:20:15,758 --> 00:20:17,758
Against a bright light.
357
00:20:17,758 --> 00:20:20,344
Sheets with fewer
Remaining contaminants
358
00:20:20,344 --> 00:20:21,827
Receive a higher rating
359
00:20:21,827 --> 00:20:23,965
And will command a better price.
360
00:20:23,965 --> 00:20:30,034
They stack the sheets
According to the grade,
361
00:20:30,034 --> 00:20:34,206
And then
It's into a hydraulic bailer.
362
00:20:34,206 --> 00:20:39,620
It presses the stack of
Rubber sheets into cube form.
363
00:20:42,275 --> 00:20:43,965
The dimensions of the cubes
364
00:20:43,965 --> 00:20:46,793
Conform to international
Packaging regulations
365
00:20:46,793 --> 00:20:50,068
So they'll fit neatly
Into containers for shipping.
366
00:20:50,068 --> 00:20:52,068
They spray the rubber cubes
367
00:20:52,068 --> 00:20:55,275
With a mix of calcium carbonate
And solvent.
368
00:20:55,275 --> 00:20:57,206
The mixture forms
A film on the cubes
369
00:20:57,206 --> 00:20:58,275
That prevents mold
370
00:20:58,275 --> 00:20:59,896
And keeps them
From sticking together
371
00:20:59,896 --> 00:21:02,103
During transport.
372
00:21:02,103 --> 00:21:05,344
This rubber is now ready
For the next factory
373
00:21:05,344 --> 00:21:07,482
And the next transformation.
374
00:21:07,482 --> 00:21:09,827
It could become almost anything.
