I think it's unlikely in this case. They seem to have gone out of their way to show a method that can achieve replication using very common materials and pretty much medieval-grade technology (except for the vacuum pump, maybe).
Ok, if that's the case, why the imperfect demonstration? Why not dozens and dozens of videos showing such a monumental success in action? The lack of clear evidence, especially with social media frenzies, is a red flag in my opinion.
