Have you watched any of those domino-falling videos? They’re really cool. I like to watch them at 2 times speed so that everything falls even faster
It would be even better to see it in person I think, thought, because watching it on video makes it hard to see everything that’s happening. There's a bunch of strings of dominoes falling in different places and the camera can’t look at all of them all of the time.
It's also kinda weird that not all the dominoes will fall when you have a bunch of them stacked up high in a tower. You'd think they'd fall down so easily!
I found a fun video of 500,000 dominoes falling, and this set-up broke 3 Guinness World Records!
