Incredible slow-motion footage of a soap bubble freezing has helped shed light on the beautiful phenomena known as the 'snow globe effect'. This remarkable quirk of physics sees tiny crystals swarm around the surface of the bubble before eventually sticking together and freezing over. Incredible footage of a soap bubble freezing has helped shed light on the beautiful phenomena known as the 'snow globe effect'. Marangoni flow sees a liquid flow from areas of low surface tension to areas of high surface tension. But a frozen surface and a soap bubble placed in a room temperature environment sees the bubble freeze from the coldest point - where the bubble is in contact with the frozen surface - and slowly rises upwards.
