Clue
THE JAR WILL BE HALF FULL IN 59 MINUTES. A MINUTE LATER, IT WILL DOUBLE AND WILL FILL THE JAR
THE DISH WAS HALF FULL AT 12.59 PM. SINCE THE BACTERIA DOUBLES EVERY MINUTE, THEN ONE MINUTE EARLIER, THE DISH MUST HAVE BEEN HALF FULL
IT WILL TAKE 1 HOUR AND 59 MINUTES FOR IT TO BE HALF FILLED
YOU WOULD NEVER FINISH IT - THERE WOULD ALWAYS BE SOMETHING LEFT TO READ IF YOU ONLY READ HALF OF WHAT IS LEFT EACH DAY
