I did an initial pull with heptane off an ACID (basified) solution... I let it evap down a bit to concentrate it. It began to get cloudy. It was in a glass dish. I picked it up and looked thru the solvent. Magical fine strings of the substance where swiming around and spiraling and being drawn to eachother and coalescing! I moved the dish from side to side and they dispersed. and then when the liquid settled, they were drawn to eachother again, spiraling, and coalescing. I covered the dish and put it in the freezer.
