This is the big 'secret' project I have planned to do for a while. I bought the dominoes originally just for this project. After three days of building, it's finally done. This took me about 18 hours to make and just over 6 minutes to fall down.
The line stopped in the beginning and I thought this was a failure. So I stopped filming and put my camera down. Luckily I had my phone filming the whole thing, because about 3 seconds after I had put my camera down, it mysteriously continued. After the falldown I found the domino that made the line stop. It was really sticky for some reason and that's why it stopped for about 10 seconds. So it's not a fail!
(Even if it was, the remaining dominoes would still be enough to make a new world record.)
The line contained 18,654 dominoes (All of my Domino Express) and that's exactly how many there is. I count them by hand and put them in stacks of 10. I also got to know how many dominoes I have.
The previous record was made by Hevesh5, berlagawesome and ShanesDominoez. I made this myself in just three days and I'm so dead right now. This beats the previous record by 3,130 dominoes.
