The "water" might have been exterminated by security when scanned.

It is the government. They should like negative numbers.

Saw a wonderful TV segment once. The producers mailed all kinds of stuff
(much had to be left on the post office loading dock with no return
address). Everything had the appropriate postage and a valid address. The
things included:

* A set of deer antlers.
* A single snow ski.
* A bottle of water.
* A small clear plastic box containing a tooth.
* Can of beer.
* A John Deere gimmie cap.
* A single tennis shoe.
* A two-foot 2x4.
* A brick.
* A plastic trash-bag containing leaves.

Most of it got delivered. The bottle of water was drunk by the postman.
