Like surface tension which turns water into a potentially deadly substance for insects.

如表，把水变成对昆虫致命潜在陷阱。

That's what creates surface tension and it has a property called cohesion.

这就是产生表原因它有做内聚特性。

How does your brain feel about calculating the surface tension of the domain walls?

那你大脑对于计算畴壁表怎么看？

Surfactants' ability to break surface tension makes them useful to humans as a wetting agent.

表活性剂打破表能使它们作为湿润剂来说对人类是非常有用。

But buoyant objects don't rely on surface tension, so they continue surfing the meniscus.

但是有浮物体不依赖于表，所以它们会继续在弯月浮动。

A buoyant object will always repel something held up by surface tension's stretchy membrane.

个有浮物体总是会排斥由表弹性膜支撑东西。

They're too dense to be buoyant, they float because of surface tension.

它们密度太大以至于无法浮起来，它们漂浮是因为表。

And that's because surface tension takes over.

这是因为表出现了。

Water can't enter it because their hairs are too tiny to break its surface tension.

水无法进入，因为它们毛发太细密了， 无法打破水表。

It would quickly engulf you, its surface tension too hard for you to break and you'd drown.

它会很快把你吞进去，由于表太难打破，你会被淹死。

This defense mechanism relies on another property of surfactants — their ability to break the surface tension of water.

这防御机制依赖于表活性剂另特性——打破水表能。

Instead, they gather into thick blobs of liquid around their eyes because the water surface tension holds tears together.

相反，眼泪在眼睛周围凝结成浓稠液体团，因为水表把眼泪聚集在了起。

Remember how I said spherical, blobby shapes minimize surface area thanks to surface tension?

还记得我说过球状水滴形状由于表而使表积最小吗？

The chemical properties of soap lower the surface tension of water, so anything relying on surface tension to stay afloat will sink.

肥皂化学性质降低了水表，因此任何依靠表保持漂浮东西都会下沉。

Surface tension happens because water molecules are more attracted to each other than the air around them.

表出现原因是因为水分子彼此之间吸引比它们周围空气对它们吸引更大。

And so the insect carries its own outside lung around and can basically breathe underwater thanks to surface tension.

所以昆虫能到处带著自己外肺。并基本上能在水下呼吸。切受惠于表。

Or the Blue Dragon nudibranch, which floats upside down in the water using surface tension and camouflages with the water.

或者是蓝龙裸鳃鲨，它利用水倒挂在水上，并利用水伪装自己。

Well, now that you can focus again, what do you say we get back to surface tension of domain walls?

现在你注意又能集中了，咱们可以回到畴壁表研究了吧？

Other aquatic insects like water treaders exploit surface tension, just like thumbtacks and paper clips.

其他水生昆虫，如水蟑螂，就像图钉和回形针样利用表。

Because the surface tension is different in space.

因为空间中表是不同。
