What is the experience of blowing bubbles outdoors at MINUS 3 degrees?

Blowing bubbles outdoors at minus 3 degrees is very beautiful and colorful.

In the freezing cold of MINUS 3 degrees, the phenomenon that bubbles freeze flowers at the moment of blowing bubbles has attracted people's attention. Behind this beautiful moment, there is actually a mystery of physics.

when the outside air temperature is much lower than the melting point of soapy water, the water vapor will quickly condense and form ice crystals when the soap bubbles come into contact with the ice surface with relatively high water vapor content. This process will release a certain amount of heat, making the bottom inside the bubble warmer and the top relatively cooler.

this temperature difference will cause a special phenomenon-"updraft". This air flow will send the newly formed "small ice crystals" to the middle and upper parts of the bubbles. Due to the relatively low temperature in the middle and upper parts, small ice crystals will further condense and grow, forming the snowflake ball effect we see.

physical phenomena of low temperature weather

1. splashing water into ice is a common phenomenon in northeast winter. This is because water freezes below degrees Celsius, and when the temperature of water is below freezing point, it changes from liquid to solid. In the cold weather in the northeast, a basin of hot water will quickly freeze and form beautiful ice flowers after it is spilled.

2. Ice flower is a unique physical landscape in winter in Northeast China. They come in different shapes, some like pine needles, some like snowflakes, and some like branches. These ice flowers with different shapes are actually different crystal structures formed by water molecules during freezing. These beautiful ice flowers are the artistic creation of nature in cold weather.

3. In winter in Northeast China, especially in the early morning, it is often seen that the treetops are covered with white and glittering frost flowers, which is rime. The formation of rime is the result of condensation of saturated water vapor in the air at low temperature. When water vapor meets a low-temperature object, it will condense into frost flowers and attach to the surface of the object. The appearance of rime adds a poetic and aesthetic feeling to the winter in Northeast China.
