F is for Fluid Dynamics. F is also for Faffing About – which is what I did for most of this afternoon.
One (slightly) interesting thing I’d like to point out about this image is that the movement trails show how far each of these tiny droplets moved in 1/200th of a second. And the other (slightly less) interesting thing is that the upper droplet was moving upwards here, rather than down.
And now I’ve run out of anything even vaguely interesting to say, so I’ll bid you all good night.
