Hi ya'll

Some dude I met on the bus is trying this and had a question. When he added vinegar to the d-Limo in his sep funnel, it seperated nicely, but after some gentle swirling it had a honeycomb of soapy looking bubbles all through it. He let it sit for a while and it looked the same, then aimed a hair dryer at it from about a foot a way for a couple of minutes, to no effect. He then jiggled the spout a bit and a whitish clump fell to the bottom, then most of the rest sank as well, with some still at the phase boundary. Every so often a tiny bit will sink or float back up, almost like a lava lamp. Does anyone know what this might be? Calcium Acetate? Alkoloids? Cactus Crap?

He gave me a picture for reference, sort of hard to see but he says it is more distinct now and the vinegar is clear to cloudy.

How should he proceed?
