Original Note:
Buoyancy is defined via the acceleration due to gravity (g in the equation below): F buoyant =ρgVf The links below summarize this: https://www.khanacademy.org/science/physics/fluids/buoyant-force-and-archimedes-principle/a/buoyant-force-and-archimedes-principle-article https://en.wikipedia.org/wiki/Buoyancy Additionally the Tweeted video shows acceleration from gravity (g), as the vacuum chamber has zero buoyancy without air or other medium.
