I have a bottle of water on my desk. I've long since peeled off the label, and I wanted to add some drink mix to the water, but I wasn't sure how much water the bottle held. I also didn't want to pour it all out into a measuring cup. So after thinking for a few seconds, I headed to the mailroom and got my answer.

Why?
