– The image shows two words: BLAST and PAST. BLAST is written vertically, intersecting with the word PAST – which is written horizontally – and sharing the same letter A. In order to reach the correct solution to this puzzle is to think about the word BLAST as emerging from the word PAST. In other words, “Blast for the past."
– A “blast from the past" is something (an event, usually) that occurs suddenly and in a powerful manner and brings back strong memories of your life, or makes you remember a past period of time from your life or others’ lives. This is also the name of a 1999 comedy movie of American origin starring Alicia Silverstone and Brendan Fraser among others.
