A mini domino is so small that it weighs only a hundredth of the weight of a regular domino. Setting them up for an orderly fall requires great concentration and precise movements. Sinners Domino Entertainment proved up for the challenge when it set up and knocked down a record-breaking 2,000 piece domino arrangement. The teenagers in this video performed this feat at the Wilhelm-Lückert-Gymnasium in Büdingen, Germany, on July 12, 2013.
Sinners Domino Entertainment usually operates on a grander scale. You may recall their domino arrangements with 277,275 pieces and the flags of the world.
