Bricklayers in Teralba, New South wales, Australia, capped a wall with perfectly-laid bricks, using a domino fall. I understand the first fall, although I couldn't understand why they did it. Then the second fall comes back around, and whoa! How did they do that? On Twitter, @neconocc gave us a graphic that helps to make it clear.
@joebloggs8040 I made a physics simulation. It works but the condition is very severe. Is there any hidden gimmick? pic.twitter.com/qJ7IktrYX3— ふぁい (@neconocc) December 25, 2016
It's pretty darn cool to watch, but I don't see any advantage to laying bricks the old-fashioned way. S till, if the purpose was to make a viral video, they did well. (via Metafilter)
I'm sure they just did it for fun. The time taken to set it all up so precisely would make it a pretty inefficient way to cap a wall. And presumably afterwards they had to lift each block and put mortar under it anyway. But it was fun while it lasted!
