Do you know what the World Record for longest domino line is? This number is difficult to imagine, but it's slightly less than 15,524 dominoes! And this very number is exactly the one that was put into a line after 2 days of exhausting physical labour (we are joking, of course). However, the fact remains unchanged - once these guys decided to break the world record they dedicated 2 entire days of their life to create the beauty meant to be ruined within a few minutes. Was it worth it? Well, watch and think of your own answer!
