The wall collapse of 30,000 dominoes assembled like a trump tower

A movie that prepares multiple walls with stacked Domino and breaks it at once in the same way as a tower made by stacking cards.

A wall is made up of 750 dominoes and 40 walls are formed. It breaks down 30,000 dominoes in all, but it is a three-dimensional movement as it is stacked up.

Details are as below. Domino is accumulating steadily


Domino used was 30,000 pieces.


I have put a cat after completion for some reason.


Start pushing the middle of the wall to break the domino.

Because it collapses easily, it is difficult to see it as if you are using 30 thousand pieces, but if you place 20 thousand pieces in a plane it will be about this.
