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.
Science - Event - Team - Virginia - Tech
The science behind the beautiful event has never been studied and a team from Virginia Tech in the US looked to understand the mechanism behind it.
Jonathan Boreyko and colleagues investigated the heat transfer processes that govern the dynamics of freezing soap bubbles.
Authors - Study - Nature - Communications - 'Droplets
The authors write in their study, published in the journal Nature Communications: 'Droplets or puddles tend to freeze from the propagation of a single freeze front.
'In contrast, videographers have shown that as soap bubbles freeze, a plethora of growing ice crystals can swirl around in a beautiful effect visually reminiscent of a snow globe.
Physics - Bubbles
'However, the underlying physics of how bubbles freeze has not been studied.'
