Postal Experiments and Hot Air

Postal Experiments details the trials and tribulations of dozens of weird, unpackaged items, all sent through the postal service:

Having long been genuine admirers of the United States Postal Service (USPS), which gives amazingly reliable service especially compared with many other countries, our team of investigators decided to test the delivery limits of this immense system. We knew that an item, say, a saucepan, normally would be in a package because of USPS concerns of entanglement in their automated machinery. But what if the item were not wrapped? How patient are postal employees? How honest? How sentimental? In short, how eccentric a behavior on the part of the sender would still result in successful mail delivery?

Good stuff, like:

Molar tooth. Mailed in clear plastic box. Made a nice rattling sound. Repackaged in padded mailer by unknown individual; the postage and address had been transferred to the outside of the new packaging. A handwritten note in a woman's writing inside read, "Please be advised that human remains may not be transported through the mail, but we assumed this to be of sentimental value, and made an exception in your case." Days to delivery, 14.

Never-opened small bottle of spring water. We observed the street corner box surreptitiously the following day upon mail collection. After puzzling briefly over this item, the postal carrier removed the mailing label and drank the contents of the bottle over the course of a few blocks as he worked his route.

This is one article from a much larger improb.com, which publishes a magazine called the Annals of Improbably Research. All good stuff.
