These workers propped a row of bricks up and then let them fall like dominoes and took a video of it—but you have to watch it to the end to understand the ingenuity.

How does this work?
As each brick falls, it is supported by the next brick and partially propped up
But when the last brick falls, there’s no such support—so it completely falls over.
This means the tiny portion of that last brick which was supporting the brick before it is no longer holding up the previous brick.
Once it falls, it causes another domino effect, in reverse.
Here’s the video from another angle:
Or if you just like watching dominoes in reverse, here is a video compilation of domino videos played backwards, by domino artists (it’s a thing) Hevesh5.
