Three YouTubers on a zero-g flight:

Physics Girl: Zero G Ferrofluid Fail. (10:48min)

Veritasium: Fire in ZERO-G!! (7:47min)

e-penser: Vol en zéro-G. (35:26min) This one is in French, but English subtitles are available.

This looks like so much fun! I would accept an invitation in a heartbeat, since tickets usually cost several thousands of dollars…
