Coke -- sink or swim?

Here's a thing.....

Q. Why does a can of Diet Coke float in water, while a can of regular Coke sinks?

A. The explanation from Coca-Cola: Diet Coke contains aspartame (Nutrasweet), which is less dense than sugar and also much sweeter, so less is needed. We would imagine that the second half of that is what really matters here. Aspartame is 200 times sweeter than sugar; if it takes 9 teaspoons of sugar (sucrose or high-fructose corn syrup) to sweeten a Coke, then it takes less than a 20th of a teaspoon of aspartame. Check out the ingredient label: There's less sweetener in a Diet Coke than there is caramel coloring.
