NEW YORK - There's a new security threat at some of the nation's military bases — and it looks uncannily like a can of Coke. Specially rigged Coke cans, part of a summer promotion, contain cell phones and global positioning chips. That has officials at some installations worried the cans could be used to eavesdrop, and they are instituting protective measures.

Paul Saffo compared the concern about the Coke cans to when the Central Intelligence Agency banned Furbies, the stuffed toys that could repeat phrases.
