What's going on here?

I have a question, have you ever seen those experiments where they drop a hammer and a feather inside a vacuum chamber and they fall at the same speed? If not here's a link https://youtube.com/shorts/GloPoezzVAg?si=b5IuUb7101syw8XE How can this be? (I have been stuck at this for 2 days)

The experiment shows the inside of an (aluminium-) drop caspule in the drop tower (110 m) of ZARM. During the fall of the test bodies (Lithium [Li], Beryllium [Be], Bor [B], Carbon [C], Aluminium [Al], Iron [Fe], Plumb [Pb]) you can see the different accelerations between the elements. But the accepted physics says that these bodies should all have the same acceleration! The drop experiment is the falsification of the UFF, of Galilei's law.
