How beautiful is the picture of blowing bubbles below zero?
Instantly produce frozen ice flowers. Because of the extremely high temperature requirements, this scene can only blow out dream ice bubbles at around MINUS 30 degrees Celsius.
The principle is that when the outside air temperature is far below 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 a higher bottom temperature and a cooler top inside the bubbles.
In this case, the temperature difference in the bubble will make the "updraft" 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 up, resulting in the snowflake ball effect. ?
