Eventually, though, a group of land animals got around the square-cube problem altogether by climbing back into the water, which buoyed their weight.

如果竹子长度或者直径不够，便不会产生足够浮力。

And I argued if one balloon provides some unit of lift, why wouldn't we be able to scale that?

我想说，如果每个气球都能提供一定浮力，那我们多用些气球不就行了吗？

Floating in space is similar to floating in water, so astronauts practise their spacewalk in swimming pools.

在太空中受到浮力和在水中受到浮力相同，所以宇航在泳池中练习太空行走。

So as you travel deeper, the buoyancy force from the metallic hydrogen counteracts gravity's downward pull.

所以当你下降得更深，来自金属氢浮力，抵消掉向下重力。

And that buoyant object did the opposite, it floated to the middle.
