Variant of a regular domino wall resulting in a faster toppling speed
A speed wall is a variant of a domino wall based on several three-domino “inverted U” shapes stacked on top of each other. It is a bit less stable than a regular domino wall and topples at a faster speed, hence the name speed wall.
Step by Step
A speed wall is built by stacking several three-domino “inverted U” shapes on top of each other as illustrated below.
