Amazing TRIPLE Domino Spiral

I spent 25 hours spread over 8 days building this massive triple spiral structure with 15, 000 dominoes. Subscribe for my best project yet :) yo give it a share for all the hard work :) FB: Twitter 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 :) Hey I m Hevesh5 and I am a professional Domino Artist.
