Ice contamination is the last thing you want to see on your cryo-EM grid, as charging of the ice under the electron beam is a common source of image drift at high magnification. However, sometimes while screening your sample it is nice to come across such a perfectly hexagonal ice crystal as seen here on day 306 of #LMB365
