What is going on at 09:22 ?

[Moontanman]

In the background of this video something really odd sems to be going on before this point they were making mercury spin with a magnetic field and interviewing some odd people but at 09:22 they start doing something really odd ,the spinning mercury is odd, but this seem to be a object that rises on a magnetic field to a quite high level, even outdoors. Anyone want to take this one?
