The fetched page metadata for that X post only provides view counts and interaction metrics, along with the teaser text: *"Here's a video that will upset globe earthers and most flat earthers too."* 

Because the actual video content, visual demonstration, or underlying experiment isn't present in the text scrape of the link, a precise forensic breakdown of its specific claims cannot be performed from the metadata alone. If you can provide a description of the experiment shown in the video, the apparatus used, or the specific physical forces and measurements it attempts to demonstrate, we can immediately dive into a rigorous, technical analysis of its mechanics.
