Why do cans of Coke have variation in their weight?

Answer 1

Packages of products have variations in the weight of their contents due to the (slight) inaccuracy in the machines used to dispense the goodies into the packaging. There are, in general, some "standards" regarding the amount of error that is "okay" in the production and packaging of products. While it is true that we may get "shorted" a bit of product in a package, it won't be much. And we have as good a chance of getting a bit of "extra" stuff next time we sample the same goods. Walk by the soda section and look at the level in, say, the two liter bottles. See the variation? How much of a difference is there? And how much compared to the total amount of the product in the bottle? Yes, accuracy could be improved, but at what cost? There is a point of diminishing returns where it just takes too much time and (more expensive) equipment to increase the accuracy of the dispensers to deliver a (more) "fair share" to you, the consumer. Make a leap of faith. Accept that companies that make products and package them are pretty straight with you. These companies don't "nickel and dime" consumers because it is far cheaper to just do a good job than to have to field angry complaints from consumers and answer letters of inquiry from consumer protection agencies. Certainly you can always get the straight scoop right from the horse's mouth. A link is provided, and they do have people who will pick up the phone or answer email. They're down with PR and good customer relations. And that's dope.
