Instructables user spookylean turned an Altoids mint box into a portable martini kit. This way, he's prepared for a martini emergency. He writes:
All you will need to be prepared in any emergency is an Altoids or equivalent tin, some tiny bottles (the smallest one is from a miniature Tabasco sauce bottle), a tiny ziploc bag, a folding paper cup (about the easiest origami there is), and the stopper cannibalized from a dollar store water pistol. Oh, and of course gin (I favour Plymouth) and vermouth (Noilly Prat).
