I know - that's the title of a Letterman segment.
But I just heard something on the radio that might work for this.
According to a random "trivia" sheet that one of the DJs was reading off, cans of Diet Coke will float... but cans of regular Coke won't.
So - any other oddities about things floating or not?

No mystery. If an object is heavier than the amount of water it displaces, it sinks, if lighter, it floats.

According to the trivia sheet, Diet Coke is supposed to be just that much lighter than regular Coke, due to something with the sweeteners.

According to the trivia sheet, Diet Coke is supposed to be just that much lighter than regular Coke, due to something with the sweeteners. The phenomena isn't just limited to Coke. I just happen to have a regular and diet can of A&W Root Beer. The diet can floats and the regular sinks. And surprisingly, the difference in buoyancy is substantial. Also a little strange, the 12 oz can of regular weights 386 grams, while the diet is 368. The last two numbers of the weight being reversed.

This raises the question as to whether or not the difference in weight is the reason why the diet variety floats. I think what might really need to happen is for someone to take the same quantity of sweetener used in each version and focus on just that. Say, for example, compare five ounces of the sweetener from the regular version up against five ounces of the sweetener from the diet variety. We could compare how much they each weighed in order to see if there's a significant weight difference, and then once we have this measurement we can see how well the different sweeteners float in water (if they float at all). If the diet sweetener floats but the regular sweetener doesn't, then we have the issue of determining why. Is it because of weight? If the weight is the same, does the chemical composition make an impact? Et cetra.

But to figure out how the different sweeteners are affecting the overall weight, you would have to know the weight density of both sweeteners and compare that to the amount of water each is replacing in the formula. Information that isn't available on the can, but I' sure someone that really gives a rip could find out.

Do you know what you just said there?..... how can 5oz of either be heavier.?.. The problem is Volume. The "recipe" calls for different volume of sweeteners to be dissolved in (typically) 330ml of fluid. The "Artificial" sweetener is considered to have more effect by volume to the taste than other sugars. Therefore, the diet variety has less weight by volume than the regular version. 330ml in a standard can with [x] airspace at the top of the can (same in both varieties) therefore weighs less in the diet variety than the standard variety. The volume of sweeteners if of course "so many sacks" which are designated by weight of the sack into each batch of liquid in the mixing... But two small "pills" of sweeteners can replace two spoonfuls of sugar in a diet persons coffee order. If you tried to put two full spoonfuls of sweetener at its basic formula into a brew, it would be undrinkable....

co the converse - compare the weight of a cup of Splenda (brand) sweetener to a cup of sugar.
or better yes, compare the weight of a quart of each, so you have enough weight from the splenda for the scale to notice.
a 9.7 ounce bag of splenda is about the same volume as a 5 pound bag of sugar.
edit: note splenda is formulated to be able to exchange volume for volume with sugar - hence the extrememly low weight to volume, but it also reduces the number of variables in the comparison.

Don't forget that you also have to consider the weight density of the sweetener compared to the water, and other stuff, in the soda. How much water (and stuff) does the sweetener take the place of in the can. If everything in the can is a liquid 12 ounces, (volume, not weight) then less sweetener may leave more water, which may make the can heavier. It starts to get a little more complicated when you also consider that one sweetener may only require a little to get the same sweetening effect as another sweetener and thus leaving more other non-sweetener stuff in the can. I'm beginning to think the real solution the the whole problem of sinking soda cans is Styrofoam coolers.

I'm beginning to think the real solution the the whole problem of sinking soda cans is Styrofoam coolers. that raises the question of whether soda is made by mixing the flavoring additives and then adding water to make up the official volume, or if it is made by taking a measured volume of water and then adding the additive mixture. my contribution is when I worked where there was a fountain that used syrup packs and carbonated its own water is that the mixing orifices were not flavor specific. therefore the syrup is made to be a consistent volume. - that would seem to imply they make it for the finished volume. - adding water to the syrup to make the right proportionate volume.

Most soda machines mix a 5 to 1, water to syrup ratio.
