An elementary school in Oregon set a new unofficial record for cereal box dominoes.  They used 6,877 boxes, and then donated them all to a food bank.  They originally planned to get Guinness involved to make it official.  But there were time constraints, so they just went for it.  They would have beaten the current record by about 500 boxes.
