THE AMAZING TRIPLE SPIRAL (15,000 DOMINOES)

I spent 25 hours spread over 8 days building this massive triple spiral structure with 15,000 dominoes. Subscribe for my best project yet 😊 give it a share for all the hard work! GET AN AMAZING TRIPLE SPIRAL POSTER! :D Worked flawlessly with no breaks! For proof, watch this structure build itself in REVERSE! Pretty sure this is an American record for longest domino speedwall too :)
