I found two empty aluminum cans this morning at school: Enviga (Nestea)
and Iced Coffee (Starbucks). These cans are thinner than the normal 12-oz
varieties. What surprised me was the labels. Enviga said 12 oz (355 mL)
while Iced Coffee said 11 oz. (325 mL).
I asked my students about this. One said Enviga was carbonated and that
maybe the volume of fluid went down after you opened the top. Another said
that the coffee was foamy, and maybe this had something to do with it.
Nobody really had any good ideas.
So if the labels state how much fluid is actually in the can, why not use
different size cans? Or is there some type of deception here?
