Detroit is so broke that firefighters get emergency alerts through pop cans, coins, door hinges, pipes and doorbells.
And, says Tresa Baldas, they make these gizmos themselves — one
involving a pop can that gets tipped over by an incoming fax. The clink
of the can means there’s an emergency. Then there’s the chain-reaction
gadget: a fax hits a door hinge, which then tugs on a wire, which then
sets off a doorbell.
