But they increase in length when 'un-dissolving' (or is that 'solving'?)
Subtleties, subtleties, subtleties ... the reaction is reversible, but it does not follow the same path.


Next time I do time lapse, I'm going to include a clock face in the frames to keep track of the flow of time. This one had a frame timing of about 3 seconds, and a total time of 85 seconds. Compressed to 5 seconds, we're looking at 17:1 acceleration.
