Ferrofluid (magnetic liquid) looks pretty but it smells like old engine oil.

How does that work?

I do not know for certain but it is what is used in Ferrari shock absorbers instead of hydraulic oil.

How does that work?

The spiral towers are electromagnets, the strength of the magnetism is varied thought the video.
The ferrofluid is a liquid version of iron filings reacting to magnetic field.

Again using an electromagnets, the viscosity of the ferrofluid can be varied, enabling electrically variable damping.
