The Double Domino Effect Demonstrated With a Row of Bricks That Fall Perfectly Into Place

Canadian math, science, and IT consultant David Petro was inspired by a video, created by Matt Parker back in March, where he explained the double domino effect. Petro decided to demonstrate the chain reaction himself by lining up a row of bricks, pushing one over, and watching as the clickety-clacking row fell over perfectly into place like dominoes.
