A message in a bottle is a form of communication in which a message is sealed in a container (typically a bottle) and thrown into the sea.
Messages in bottles have been used to send (1) distress messages and/or to carry letters or reports from those believing themselves to be doomed (2), in scientific studies of ocean currents, as memorial tributes and (3), to send deceased loved ones’ ashes on a final journey.
Love letters have also been sent as messages in bottles. Indeed, the lore surrounding messages in bottles has often been of a romantic or poetic nature.
Nowadays, the phrase, message in a bottle, has expanded to include metaphorical uses (uses beyond its traditional and literal meaning). Say for example, sending an estranged lover an email begging for a reprieve whilst knowing a reply, let alone a reprieve is rather unlikely.
