How beautiful is the picture of blowing bubbles below zero?

Blow bubbles in sub-zero weather. The process of bubbles slowly freezing will form a very spectacular scene. The ice is transparent and bright, shining brightly under the sun, and as beautiful as a rainbow. You can also try one if you have a chance.

instantly produce frozen ice flowers. Because of the extremely high temperature requirement, this scene can only blow out dream ice bubbles at about MINUS 3 degrees Celsius.

The principle is that when the outside air temperature is much lower than the melting point of soapy water and the soap bubbles contact the ice surface with relatively high water vapor content, the water vapor quickly condenses to form ice crystals and releases heat, resulting in higher temperature at the bottom and cold at the top of the bubbles.

in this case, the temperature difference in the bubble will cause the "updraft" to appear, so that the "small ice crystals" initially formed at the bottom of the bubble are sent to the middle and upper parts of the bubble, and further condense and grow, resulting in the snowflake ball effect. ?
