AltUse Find - ChapStick® as a Spy Tool

The Double Secret Life Of ChapStick Lip Balm

1972 saw the ubiquitous ChapStick pressed into service as a spying tool.  ChapStick tubes were modified with hidden microphones and were used by G. Gordon Liddy and E. Howard Hunt during the time of the Watergate break-in.  I couldn't find any details of how exactly to use these microphones - I'm guessing that the operator would hold them in his hand with the wires running up his sleeve.  If you look closely, you can see a pushbutton on the body of the ChapStick, which must be a clue.  I'm guessing a push-to-talk button like on a walkie-talkie.  Loose lips might sink ships, but at least they won't be chapped while doing it.
