The reason this didn't show the rotation is in the Top Comment in the Youtube comments: friction. The unit was not manufactured to detect the motion of earth spinning. The first min of this vid explains the problem gyros have with the task (

Did you even watch the vid I posted for you? Covering a $20k laser gyroscope purchased by FEarthers, that could detect earth rotation, with the hope that it wouldn't, but it did?

One needs to ask oneself? "Do I want earth to be flat (for some reason)? Yes or No
If 'yes', you have to acknowledge and take head-on your own confirmation bias.
If want a bunch of dudes with no science degree or training to make a youtube vid "proving" earth is flat with faulty premises, formulas and gear, you can find it, and they want your funding. But is that really the right place to start if you want to find reality and truth?
If you want reality and truth, and avoid falsehood and cult trappings, then start with the science that has been discovered, confirmed and built upon over centuries by scientists -- as I discovered by science historian (christian) Stephen Meyer -- scientists who were dedicated christians who's stated reason for their scientific pursuits was to discover God's creation. The vast majority of today's science knowledge, including the reality of the spherical earth, was done by the research of christians.
Start with learning the current confirmed knowledge built over centuries, so you at least have a basis for seeing thru FE cult junk science falsehood vids.
This is merely ONE of the basics of how spherical earth was confirmed:
