If you’re bored of hard-boiled eggs having a yellow centre and a white exterior, then you’ll want to pay attention to this wacky recipe for inside out eggs.如果你已经厌烦了里面黄色外面白色的水煮蛋，那么你一定想好好看看这个不走寻常路的食谱，教你如何制作蛋黄在外、蛋清在内的鸡蛋。
A Japanese chef revealed a method to reverse the colour of your eggs in a YouTube video.
在YouTube的一段视频中，一位日本大厨揭示了这种调换蛋清蛋黄的方法。
Using a few bits of equipment found around your home - including a pair of tights and a torch - you too can enjoy the novelty of a boiled egg that has its white albumen on the inside, and its yellow yolk on the outside.
用几样在家里就可以找到的工具（包括一双丝袜和一个手电筒），你就可以拥有这种新奇水煮蛋，白色的蛋清被黄色的蛋黄包裹在里面。
The science behind it is that the yolk of the egg is more dense than the albumen.
这种现象背后隐藏着科学知识，也就是蛋黄的密度比蛋清的密度大。
When you spin the egg rapidly, the runny yolk is drawn towards the edge of the egg via the centrifugal force, while the albumen is pushed to the centre.
当你快速旋转鸡蛋时，蛋黄收到离心力而流向蛋壳，蛋清则被挤到了中心部位。
If you spin the egg for long enough, the yolk and albumen separate, so that when boiled the egg appears inside out.
如果旋转鸡蛋的时间够长，蛋黄和蛋清就会分离，这样再煮，就会得到蛋黄在外、蛋清在内的鸡蛋了。
If you don’t spin it for long enough, the two mix so that you get an instant scrambled egg.
如果旋转的时间不够长，那么你做出来的就是即食炒蛋。
What you'll need: An egg, clear tape, a torch, a pair of tights and ice cubes.
你需要：一只鸡蛋，透明胶带，一个手电筒，一双丝袜和一些冰块。
1. Check the colour of your egg with a torch.
用手电筒照一照，看看鸡蛋的颜色。
2. Put tape around the whole shell of the egg.
用透明胶带把整个蛋壳缠一圈。
3. Wrap it in the middle of a pair of tights.
把缠好胶带的鸡蛋塞进丝袜里。
4. Spin it round for a few minutes by holding either end of the tights.
抓住丝袜两端，旋转几分钟。
5. Check on the colour again. It should be darker than in step one.
再检查一下鸡蛋的颜色，应该比第一次看时颜色深。
6. Take the egg out of the tights and place it in boiling water with the tape still on.
把鸡蛋从丝袜中拿出来，不要拆掉胶带，直接放到开水中煮。
7. Once boiled, remove the egg and place it in a bowl of ice for a minute.
煮沸后，把鸡蛋拿出来，放到装有冰块的碗中冷却一分钟。
8. Now peel the shell, and you should now have an inside out egg. If the whole thing is yellow, try it again but spin it for longer.
剥掉蛋壳，你就做好了一个蛋黄在外、蛋清在内的水煮蛋了。如果整个蛋都是黄的，那么下次做的时候载旋转久一点。
