时差N小时 无糖可乐和含糖可乐(下)

Real sugar has a high molecular¹ density².

真正的糖分子密度高，

In other words you can think of sugar molecules³ as being thickly packed together.

也就是说糖分子紧密地排列在一起。

This also means sugar molecules themselves will be relatively⁴ heavy, even when dissolved insolution.

即使溶解在溶液中，相同体积的糖更重。

In the case of the sinking Coke, the real sugar content is acting⁵ as an anchor for the can.

实验中沉下去的普通可乐，正是因为糖成分像锚般让罐子下沉。

There's also the fact that Nutrasweet is much sweeter than sugar, and so less is needed per canto⁶ achieve that recognizable Coca-Cola taste.

代糖比糖甜，所以更少的代糖能达到普通可乐的甜味。

Thus the bobbing Diet Coke not only has a lower average density, it also has a lower mass-there's less "stuff" dissolved in the mixture.

这样水中摇摆的无糖可乐不仅平均密度更低，质量也比普通可乐轻-因为更少的代糖溶解在可乐中。

If you were an advertising⁷ executive, you might want to market diet sodas⁸ as "Light"-it wouldn't be far from the truth.

如果你是广告商，你可以这样宣传-无糖碳酸饮料的优点：轻。这可没有说大话。
