I've pitched them with the scenario that they are passengers on board the Titanic who overheard the captain and ship designer saying that the boat has just hit an iceberg and will crash in less than two hours. They must write a letter to a loved one, telling them about the voyage and explaining their feelings. They will then put it in a bottle and send it out into the Atlantic Ocean.

Just a quick note to anybody downloading this - the total line should read (/18) not (~/15). Apologies!
