ISM Close Up South America Section - 25,000 dominoes 

I am dominofan0803 from Germany and I set up domino chain reactions since 1998. In summer 2016 DominoERDMANN and I traveled to America and we participated in the Incredible Science Machine World Edition. We were responsible for the South America Section.
Thanks to DominoERDMANN for editing this video.
