Real sugar has a high molecular density.
真正的糖分子密度高。
In other words you can think of sugar molecules 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 relatively 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 acting 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 canto 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 advertising executive, you might want to market diet sodas 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。
