to test if naming a ship "unsinkable" dooms it.
get small ship as found in ship in a bottles
put it into a sealed, plexiglass pill shaped ampule with a gps tracker, make sure it floats and cast it into the ocean near a place where the currents carry far.
monitor it's progress.
will the ship carry on riding the waves indefinitely until it's pinger runs out of battery, or will it suffer a premature horriffic end simply for the hubris of being named "uss unsinkable"?
