Scientists have studied the ‘snow globe effect’ which sees tiny snowflakes forming on the surface of a soap bubble as it freezes over. This is a result of the ‘Marangoni flow phenomena’. Put simply, the Marangoni flow is when liquid flows from areas of low surface tension to areas of higher surface tension. As the temperature lowers and ice crystals begin to form, the Marangoni flow causes the crystals to move away from each other and swirl around the bubble individually. When all the crystals b
