Hi Beatriz, Very interesting indeed. Couldn't it be the ghost printing of some mechanical part used to make the mould of the crystallization tray ? All the best, Philippe Philippe BENAS, Ph.D. ARN UPR 9002 CNRS IBMC Strasbourg 15, rue René Descartes F-67084 STRASBOURG cedex +33.3.8841.7109 E-m

Artem (and Beatriz), Me bad, could have thought about that! I think you are right. There were initially bubbles in each drop (7 in one case, 4 in the other). At some point the bubbles exploded (it was an instantaneous process, not just shrinking). Kind regards, Sergei Prof. Sergei V. Str

May be, I do co-relate your crystal pic with Manu Prakash at Stanford on his work on Dancing Droplets, briefing the surface tension and evaporation ^ the rule of two component fluids. # Since your precipitant contain PVP a shape controlling agent #https://med.stanford.edu/news/all-news/2015/03

Thank you all for the interesting comments and information about bubbles behavior and dancing droplets! Unfortunately, for now, I won´t be able to further investigate the process (by reproducing the crystallization setup under a camera as suggested by Philippe Dumas), but I will keep this in m
