In this youtube, a young man sits down at a table and begins singing backwards (I won’t spoiler the video for you by naming the song), while undertaking a variety of time-bound activities — popping balloons, knocking over a Jenga tower, pouring liquid, etc. At the halfway mark, the video rolls again, in reverse, with all those time-bound effects doing that cool liquid-pouring up/balloons unpopping thing, ostensibly to prove that he really did learn the song backwards, but really, I suspect, because it makes for a great visual accompaniment to this chap doing his backwards singing thing, which he does very well.
