Watching a bunch of dominoes fall in all sort of set-ups is pretty awesome.  The time involved to set them all up in their intricate patterns is amazing.  Watching them fall is more amazing.

 

How about people?  People on mattresses!

There's a world record for everything, and "human dominoes" is no different.

I know, it's crazy, but these guys did it.  Watch this group of 850 people breaking the world record for most human dominoes (with mattress).

Okay, you're up. Want to give it a try?
