How is the ice ribbon that wraps around in the air created naturally?
In January 2007, a photograph was taken in Canada of a ribbon-like thin strip of ice that swirls in the air. Professor James Carter of the Department of Geography and Geography, Illinois State University, explains this mysterious phenomenon.
Ice Formations Diurnal Freeze-Thaw Cycles
The following three pictures are the ice ribbons actually taken. Ice shaped like a translucent ribbon is wrapped around a fence with a sign that says 'Cave canem'.
The first photo taken from a different angle. The width of the ice ribbon is about 1 inch (about 2.5 cm), and you can see that the surface has a striped pattern parallel to the ribbon.
Below is a picture of where this ribbon grows. The iron fence is hollow, and it seems that the weld gap is coming out of the hole that has been opened due to deterioration and widening due to rust.
And the picture below is a picture of a ribbon that grew from the same place on another day. Ribbon-shaped ice with a striped pattern is generated.
Similar phenomena have been confirmed outside of Canada. For example, the picture below was taken at the railing of a spiral staircase in England, where a thin tube of ice swirls in the air.
Also, at the playset installed in a Russian park, ice with a beautiful spiral like a corkscrew was photographed. Both British and Russian ice come from the gaps in metal pipes.
As an experiment, Professor Carter prepared a metal pipe, filled it with water, and attached a screw cap to one side. At this time, he said that he made a hole in the cap and made a cut with a bow saw. After crushing the other flat, wrap it with duct tape to reinforce it. The pipe was placed upright outside and frozen.
And the picture below is taken. It is said that the frozen water expanded and pressure was applied inside the pipe, and the pressure was concentrated in the cracks of the cap, resulting in the formation of ice so that it would be pushed out from the cap.
Below is the ice ribbon reproduced in another experiment. Professor Carter said, 'For some reason, water gets into the iron pipe, and by repeatedly freezing and melting in the pipe, ice is pushed out from the hole in the weld mark and an ice ribbon is formed. It will be done. '
Professor Carter predicts that this phenomenon will occur because of the climate in which the water freezes due to the outside air, such as Vancouver , Russia, and the United Kingdom, where he lives. Also, according to Professor Carter's research, it seems that the colder the temperature, the more brittle the ice ribbon is.
