Marble Running Through the Whole House and Outside!

I love watching videos where someone has put together like a ten thousand dominoes in a giant stack and knocking them over, or building a huge house of cards and watching it fall once they’ve finished it.

Scott Smith loves to build super long marble tracks, and this one he’s called the Great Adventure marble run.

It goes all through his house, even out the window on the second floor and he’s got tracks hanging from his roof going to the trees in his backyard and all the way around to the front of the house again.

It’s a lot of fun to watch!
