Watch bubbles FREEZE in slow motion
Video was directed by Leila and Damien de Blinkk in Whistler, Canada. They used 4K cameras to record crystal-like structures of ice forming. As these structures spread, they are shown creating a solid outer shell. Film then records bubbles shattering, and shards of ice falling to the ground.
An incredible phenomenon has been captured on video for the first time as washing-up bubbles are shown freezing in mid-air.
The footage, filmed on cameras four-times sharper than HD, shows a group of children blowing the bubbles in a Canadian forest.
As the bubbles hit the air, they crystallise and turn into hollow blocks of ice in slow motion.
When a bubble is blown, the air inside it is warmed by the air in the blower’s lungs. As this warm air hits the cold air, it contracts to set the surface of a bubble. This surface is pictured freezing.
No matter what shape a bubble creates when its first blown, it eventually forms a sphere to minimise the surface area of the structure. This shape uses the least energy to form.
Glycerin, C3H5(OH)3, is used to extend the life of a bubble by forming hydrogen bonds with water, slowing down how quickly it evaporates.
When a bubble is blown, the air inside it is warmed by the air in the blower’s lungs.
As these structures spread across the bubbles, they are shown creating a solid outer shell (pictured). A bubble is formed when a layer of water molecules is trapped between two layers of soap molecules. In extreme temperatures, this water layer freezes first, followed by the soap layer.
No special effects or editing were added to the bubbles and the films were shot in real-time before being slowed down. In one shot, an icy bubble is shown as tough enough to be held in a hand (pictured)

In extreme temperatures, this water layer freezes first, followed by the soap layer – making the walls of the bubble more structurally sound and visible.
The advert was filmed to promote Sony’s range of Sony 4K Ultra HD TVs and the soundtrack was performed by Sony artist Josef Salvat.
Director, Leila de Blinkk said: ‘We were blown away by the beauty of the intricate patterns that the freezing of the bubbles’ surface was creating at very low temperature. The feather, flower and star ice shapes were so delicate and mesmerising when they reflected light.
