Interesting YouTube videos

Yes, YouTube does have some decent scientific and cool videos if you do the right searches (and ignore the comments)…

Ferrofluid influenced by changing magnetic fields.

Constarch science.  Newtonian fluids reacting under resonant frequencies.

Resonance.   Cymatics.  The work of Dr Hans Jenny.  Ignore the voice over and enjoy the visuals.

The above video encouraged me to try and simulate a similar effect.  Track a bunch of particles sitting on a simulated vibrating sheet (ripple tank).  Particles fall to the nearest neighbour pixel location that is lowest in height.  Results are nowhere near as impressive, but does show some potential.

And finally, my own YouTube gallery is here.
