First and foremost do not try this without the supervision of a professional.  And here is a bit of backgroung on ferrofluids from wikipedia:

A ferrofluid (portmanteau of ferromagnetic and fluid) is a liquid that becomes strongly magnetized in the presence of a magnetic field. Ferrofluid was invented in 1963 by NASA’s Steve Papell as a liquid rocket fuel that could be drawn toward a pump inlet in a weightless environment by applying a magnetic field.^[1]

We hope you like the video.  And do you think superconductors are going to be used in more applications?  Feel free to comment on it.
