1
When astronauts go up in space, they're allowed to bring some special items.
2
Some astronauts fly M&Ms, some people fly beef jerky.
3
Don Pettit, this guy, chose candy corn.
4
He's a NASA astronaut who spent nearly half a year floating around the International Space Station.
5
And while he was up in space...
6
I elected to spend my off-duty time doing science of my own design.
7
this zero gravity candy corn demonstration.
8
It's a macroscopic analogy to how a surfactant molecule works.
9
And a surfactant molecule just means...
10
Soap.
11
So in this demo, a candy corn is equivalent to a soap molecule.
12
And this water blob represents grease or oil.
13
And basically the demo shows how soap cleans grease.
14
Soap molecules have a water loving end...
15
So they call that hydrophilic...
16
And a water water-hating end.
17
Hydrophobic.
18
And that's important.
19
Say you have a blob of oil and you throw it in a washing machine, the hydrophobic part of the molecule sticks into the grease and the oil,
20
and the hydrophilic part pokes up into the water.
21
In candy corn, the hydrophobic, hydrophilic sides are reversed.
22
This part is water-loving, and Pettit coated this side with oil to make it water-hating.
23
But the principle is the same.
24
The molecules or the candy corn arrange themselves around the glob based on attraction or repulsion to water.
25
Of course, that's how your clothes get clean.
26
You cover them with these hydrophilic, hydrophobic molecules called soap.
27
And once the soap molecules fully cover the grease blob, it becomes water-soluble.
28
It's called the critical micelle concentration.
29
Or in candy corn.
30
The critical candy corn concentration.
31
Once it hits this concentration.
32
All the dirt and the oil and the grease floats off of your fabric, and it mixes with the water, and then you pour the water off, and you're left with clean clothes.
33
Now in candy corn, there's a bonus science lesson.
34
After you reach the critical candy corn concentration, And a most amazing thing happens.
35
The blob goes from smushy to rigid.
36
You can think of it like...
37
Of putting the keystone in a Roman arch, where now all of a sudden gravity locks all the stones together, and you have this rigid arch that you could drive traffic across.
38
But we're in space, so it's not gravity at work.
39
It's surface tension holding the ball together.
40
This was one of many experiments Pettit did in space, but it's the only one that used candy corn.
41
I used our whole crew's supply of candy corn for this one demonstration, which I profusely apologized to the rest of the crew because they didn't get to eat any.
42
For Science Friday, I'm Flora Lichtman.
43

什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
