128,000 Falling Dominos Makes A World Record

Here is a bit more information on the basics of most dominos.  In this video they use mostly standard dominos but configure them in an unusual way:
A typical domino is just under 2 inches tall, 1 inch wide, and about one-quarter of an inch thick. These dimensions create a thin block that’s just stable enough to stand upright yet unstable enough to fall over with the slightest nudge.
“If you make them too thick, for instance if you had dominoes like cubes, they would never [fall],” said physicist Hans van Leeuwen of Leiden University in the Netherlands.
We hope you like the video.  Have you done any experiments with dominos yourself or have any creative domino arrangement ideas?  Feel free to comment.
