More diamagnetic levitation movies...
The 'disproof' of magnetic levitation only applies for static charges. This video gives a quick demo of how you can test this yourself (I've never heard the audio track, so don't know if it's any good).
If you have a big enough magnetic field for its ρ/χ, you can levitate pretty much any living thing. Armed with this knowledge, biophysicists can conduct useful research like this and this.
