The most useless things

You know, I'm still thinking about milk. but this time, more about bottles of milk- do you know the little plastic piece right below the cap? what purpose dose it serve?!? Think about it. if we just got milk in little baggies, we would save so much material- and it would probably cost companies less anyways. And milk is not the only thing- look around you. see if you can find one of the most useless things. my blog does not count.
