I am not a flat earther.
However, all of these recent videos are believed to be filmed on a sound set at NASA or China or the Sonic Roller Coaster.
There are groups out there that take these videos apart.

Like, pointing out water bubbles during the space walks, incorrect reflections, etc.

Very interesting. Do you mean this? https://io9.gizmodo.com/5885322/if-you-have-50-million-this-roller-coaster-that-simulates-weightlessness-could-be-yours

Looks to me like this roller coaster is not yet even built.

And even if you had some tool to simulate weightlessness in the space station tour video, how on earth (pun intended) do you sustain that for 30 minutes?

If this video is fake, I'll take my hat off for NASA because that is brilliant.

I may have the name wrong.

It is just a passenger jet with no interior. And it flies in a sinusoidal path. So, on the downward side, everyone in the plane is weightless. There are all kinds of ThemTube videos with people doing all kinds of amazing things.

And there are videos calling out all kinds of errors in these productions made by NASA and china.
There really are air bubbles (because some are filmed underwater) and there are reflection and CGI errors.

What is the worst, is that there is a community that points out all these errors, and then NASA fixes them.
