神奇的镓金属与易拉罐的反应

Amazing - What Gallium does to an Aluminium Can

我听说过如果你把液体的镓金属
I’ve heard that if you put liquid gallium metal
放到铝上
onto aluminium or aluminum as you may call it,
镓在某种程度上会被铝吸收
the gallium is sort of absorbed by the aluminium
形成一种新的易碎的 柔软的合金
and it forms a new alloy which becomes really brittle and soft.
所以我觉得我可以用可乐罐来试一试
So, I thought I’d give it a go with this Coca can.
我希望可乐罐顶部是封闭的
I wanted to leave the top closed.
所以我小心地用刀在可乐罐上刺几下
So I carefully pierced it with a knife a couple of times,
这样就可以把饮料放出来了
to empty out the drink.
然后我在注射器中放满了
Then I filled up a syringe with liquid gallium
加热至融点的液体镓
which I had warmed to melting points,
然后像这样在可乐罐顶部挤出适量镓
and made a pool of it on the top of the can, like this.
看起来真酷
It looks really cool.
然后让它静置几小时来观察发生了什么
And I left like this for a few hours to see what happens,
当我回来看时镓凝固了 但是看起来并没有什么不同
When I came back, the gallium had set and it didn’t look much different.
我把镓去掉
I removed the gallium.
看起来真是跟以前丝毫不差
And it looks absolutely no different from before,
我试着用手指往下压
I tried pushing it with my finger,
又试着用螺丝刀压
and a screwdriver
但是它看起来跟刚开始的时候一样坚固
and it seems just as strong as it was to begin with
加入镓并没有改变什么
adding gallium hasn’t changed it at all
我看了下这个可乐罐
I had looked at the can,
并没有明确说明这是由铝制成的
a rather than specifying it was made from aluminium,
它上面只是写了“金属”
it just says metal,
所以我在想 这个罐子是由不受镓影响的合金做的
so I wondered if it was an alloy which was unaffected by the gallium.
所以接下来我找了一个红牛罐子
So next I found the RedBull can,
值得注意的是 这是由铝做成的
does stay, it is made from aluminium,
所以我把饮料倒进碗里
so I drained it out into a bowl.
然后重复把镓倒在顶部的实验
And repeat the experiment by adding gallium to the top,
[音乐]
[Music]
静置几小时
I let it sit there for a few hours
当我回来看的时候 把镓拿开
and when I returned, I removed the gallium.
罐子一点改变也没有
The can seems absolutely unaffected,
并没有变得脆弱 和以前一样坚固
it hasn’t been weakened, and it’s just as strong as it was before.
我决定再试一次
I decided to try one more time,
所以我再一次把红牛和可乐罐倒空
so I emptied the can of RedBull and the can of coke again.
但是这一次 我用一些砂纸
But this time, I took some sandpaper.
像这样来打磨一下红牛罐子的顶部
And use it to scratch up the surface of the can like this,
[音乐]
[Music]
可乐罐子也打磨一下
I did the same to the coke can, too.
这样就能防止罐顶的铝被其他金属覆盖
just in case that there’s a coating on top of the aluminium,
进而阻碍了镓的渗透
which stops the gallium from penetrating.
我在两个罐子顶部各滴一滴镓
I added a drop of gallium to both cans,
静置一会 看看发生了什么
and left it to see what happened,
一个小时过去了 看起来似乎有了改变
over the next hour, it seemed to change.
镓被铝吸收了
It was absorbed into the aluminium,
并且改变了结构
and appeared to change the structure
我把可乐罐拿起来
I took the coke can,
用手指捅一捅
and gave it a poke with my finger,
让我惊讶的是 我能直接在上面捅出一个洞来
and to my amazement, I was able to poke a hole straight through it.
这个可乐罐子变得十分柔软而易碎
The can had becomed soft and almost stretchy.
[音乐]
[Music]
你可以像这样把顶部撕掉
You can just sort of tear off the top,
用手指卷它
and roll it up with your fingers,
很酷 是吧
Pretty cool, huh?
我接着拽 把整个顶部都掀掉了
I kept pulling and removed the whole top,
[音乐]
[Music]
这个可乐罐的其他部分并没有受到影响
The rest of the structure did appear unaffected,
我的手指上沾满了这种银灰色的东西
my fingers were covered in this silvery gray coating
这是无毒的 很容易就能用肥皂水洗掉
which is non-toxic and easily washes off with soapy water.
接下来 我要看一看红牛罐子
Next, I have to look at the RedBull can,
这上面依然有一大滴镓
there was still a big drop of gallium on the top,
所以我把它拿开
so I removed that,
捅一捅
and gave it a poke.
[音乐]
[Music]
是的 这个红牛罐子也变得柔软易碎了
And yes, it too had become soft and brittle,
[音乐]
[Music]
并没有可乐罐那么软
not as much as the coke can,
但是这可能是因为我磨的不够好
but maybe the area that I sanded down wasn’t as big.
(拿下它的顶部)不像可乐罐一样方便
It’s not as flexible as the coke can was,
但它确实变脆弱了 我都能把它撕下来
it really is brittle and I can just tear pieces off.
[音乐]
[Music]
再一次重申 红牛罐的其他部位没有受到影响
Again, the rest of the can does seem unaffected,
但是我不久后会试一试用整个罐子做实验
but I may have another go soon and try making a whole can
这样我就能让整个罐子都溶解了
which I can just scruff and dissolve.
