The experiment that is being run is to attempt to make crystals by the string in solution method out of solutions of sugar and salt dissolved in both acetone (100% according to the bottle) and distilled vinegar (5% acetic acid). After more than 48 hours the only changes we've seen is a noticeable reduction in the volume in all 4 containers, but more so in the acetone containers, and little crystals of salt above the original line in the vinegar/salt solution.
Of course it may just be too early to see any seed crystals forming by this method.
