I expected the hardwood to be faster than the felt because the rotational moment of inertia when spinning around the center is 1/4th that of tipping on the edge. I was wrong in this case, but I'm wondering if this would hold true on glass?

THANK YOU EVERYONE who helped reduce the data! Names at bottom of this description. Follow the SED subreddit and other stuff if you want to help with stuff like this in the future. Here's the link and spreadsheet to see how we did this:

Rotational Inertia of falling dominoes can be calculated with this.

There are several papers on dominoes out there... but none really touched on the stuff I'm talking about in this video. Please feel free to point me to sources if you've found them.
