World's Longest Single Domino Line

Domino master Hevesh5 (Lily Hevesh) and friends Berlagawesome and ShanesDominoez
set up 15,524 dominos to fall in a single line. It took two days to set them up, and when they successfully fell, it became a new world record.

I am impressed with how they planned this pattern -or lack of pattern- and set it up. There’s no way to do the setup in sequence, since there’s not room to stand among the loops and whirls. And they all managed to fall without tripping up dominos out of sequence. Groovy. -via Tastefully Offensive
