This month's Challenge Question: Specs & Techs from
GlobalSpec:
A
can of a diet refreshment (such as a Diet Coke) and a can of regular
refreshment (such as a regular Coke) are placed inside a bucket of water. Both
cans contain exactly the same volume of liquid and the cans are identical in
size and shape. Which can will float higher relative to the other?
And the answer is:
Sweetening
regular soft drinks requires large amounts of sugar. The sugar will be
dissolved in the liquid with only a small increase in volume. Remember also
that the density of sugar water is greater than that of regular water. Diet
drinks require artificial sweeteners to sweeten the drink, but a very small
amount of the artificial sweetener will suffice. So the diet drink density is
slightly heavier than regular water. Therefore the regular Coke will sink, or
will at least float lower than the diet drink.
