english: We're going to go on a dive to the deep sea, and anyone that's had that lovely opportunity knows that for about two and half hours on the way down, it's a perfectly positively pitch-black world.
non_english: Ponoríme sa hlboko pod hladinu mora. Každý, kto mal túto jedinečnú príležitosť vie, že po zhruba dva a pol hodine klesania nastane absolútne tmavý svet.
