Marble Mountain is a large marble machine that is currently still under construction. It consists of 25 sections that mesh together to form one kinetic sculpture.
Every element is themed to an aspect of YouTuber Ben Tardif’s life, or to something that he finds interesting. Some of the elements include a roller coaster, ski jump, Times Square, Lombard Street, and a skatepark.
Each piece is completely custom, and it stands eight feet tall
There are 32 possible paths for the marbles
It takes at least 250 marbles to keep it running without delay, but looks better with 300

According to Ben Tardif, “it took 3 years to get to this point of being able to turn it on and watch it go, and I will continue to work on it and get it fully completed.”
