“42” is hidden in the “Best before” date, as February 11th is the 42nd day of the year.
The barcode is a distraction, resulting in the phrase “These aren’t the words you’re looking for…” when processed by a bar code reader.
Got still no idea why this phrase sprang to my mind.
The “words you’re looking for” (Practice Random Kindness and Senseless Acts of Beauty), are contained inside the ingredients list. Look up each ingredient in the Periodic Table of the Elements and write the resulting letters down as many times as the percentage states (no percentage means: once). Now you might need a good anagram generator. đŸ™‚
