I mean, we could spy on people without being noticed

how to utilize full-sized mirrors to bend light

in order to create disappearing illusions.

照相機也可以拍攝你背後的景象

都沒辦法讓一個真人大小的物體

appear invisible for all angles and distances

從所有角度和距離看 都保持隱形

To move around undetected by other people,

要在別人無法察覺的情況下行動

你的錢包和鑰匙在空中飄浮移動

Drivers and people on the street can't see you either,

therefore they can and will run into you at some point.

And, just because you start off invisible,

But if you think only liquid can make you visible,

如果你以為只有液體會讓你現形

Dust consists of dead skin cells from humans,

Dust sticks to the moisture on our skin when we sweat

我們流汗時 灰塵會附著在潮濕的皮膚上

and the tiny hairs on our skin when we are dry.

dust would still land on every part of you.

We usually don't notice the dust on our skin

我們通常不會注意到皮膚上的灰塵

because we can't see a thin layer of dust

people would see a human-shaped blob of dust

大家就會看到一個覆滿灰塵的人型

walking around with extremely dirty soles.

catch the light reflection for your brain

instead of bouncing off you for people to see.

並不會有任何反射讓人們看到你

as of whether the invisibility is permanent?

If it is, how can you receive medical treatment

For that matter, you can't see it either.

I mean, what if you have an illness or an infection?

醫生看不到顏色的改變或是發炎的情況

without being able to see the color change or inflammation?

And what if everyone is permanently invisible?

Well, think about how boring the world would be
