These repel each other
這些會相互排斥
And their repulsion causes the polymer which starts out wound together
它們的排斥會讓最開始纏繞在一起的聚合物
to unwind, swell, and stretch
解開纏繞，膨脹拉伸
The crosslinks which connect the polymer chains together
將聚合物鏈連在一起的交聯
prevent them from breaking apart in the water
會阻止它們在水中斷開
And the fake snow that's created is the same snow they use in Hollywood movie sets
好萊塢電影中用到的也正是這些人造雪
Now let's watch Dr. Dolhun and Arielle
下面再看Dolhun博士和Arielle
turn this same polymer into something totally different another
將這種聚合物轉變為完全不同的東西
OK, so I've got another beaker she's holding
這里她拿著另外一個燒杯
I'm gonna pour some water in it
我將把水倒進去
and observe
看好了
Turn it over, Arielle
把它倒過來 Arielle
You don't have to hold your hand under the whole
杯口不需要用手堵著
That's the same polymer
這是相同的聚合物
Only this time
只不過這次
the polymer is not as crosslinked as the first one
聚合物沒有像第一種那樣交聯在一起
It's more of the straight chain polymer
它更多的是一種直鏈聚合物
and it can absorb many more times its weight in water
它能吸收比自己重量大很多的水分
You'll recognize this. This is the diaper polymer
這個你們應該知道，尿布中用的就是這種聚合物
You know now, right?
你們現在知道了，對吧
So Dr. Dolhun uses the same polymer
Dolhun博士使用了相同聚合物
with a different amount of crosslinking
唯一不同的是交聯數量
The sodium polyacrylate that makes diaper gel has fewer crosslinks
用于制造尿布的聚丙烯酸鈉，交聯較少
and therefore can absorb more water
因此能夠比
than the sodium polyacrylate that turned into snow
造雪用的聚丙烯酸鈉吸收更多水
Overall, this polymer can absorb up to 800 times its own weight in distilled water
這種聚合物能夠吸收多達800倍自身重量的蒸餾水
and about 30 times its own weight in urine
以及大約30倍自身重量的尿液
It's the main ingredient in baby diapers
它是嬰兒尿布的主要成分
used to keep the baby dry
用于幫嬰兒保持干爽
