Melanie, played by Reich Witherspoon, is a fashion designer who lives in New York in a 2002 film called “Love Back to Alabama”. But before she married her fiance from the upper class, she had to go back to Alabama, in the southern part of the United States, where she came from and where her husband lived.

Glass trivia:Is glass really liquid?

In this film, liquid glass is the main element that drives the plot. While Melanie wants to be a real New Yorker, her old love, Jack Brie, also runs a lucrative business. Before the storm comes, he will fill the beach with lightning rods, and when lightning strikes the lightning rods, it will lead to sand. Lightning turns sand into glass sculptures. And when the lightning ends, it’s Jack’s harvest time. He cleans the works left by nature and sells them in galleries. Melanie didn’t know it until she gave up her fiance and returned to Alabama and fell in love with Jack again.

In this film, besides Melanie’s love life, there are many issues worthy of attention. The lightning sculptures Jack sells may come from real life, but they are full of film and television fiction. The sculptures shown in the film look like glass blowing. The works are full of abstract inspiration. The hands of the producers seem to have magic power. However, in reality, glass is not so exquisite in appearance and interior. If lightning strikes sand containing silicon and quartz, the temperature of 1,800 degrees Celsius (3,272 degrees Fahrenheit) will rise from the ground and melt the sand into quartz glass. This kind of glass, also known as lightning pipe stone, is usually a hollow tubular object whose branches radiate outward from the center and the overall shape looks like floating wood.

Whether the final state of glass is lightning pipe stones, windows or mirrors, they are initially sticky and ductile materials. Glass is initially almost liquid, made up of heated silicon, sodium carbonate, lime and magnesium oxide, which are then moulded and cooled.

Although overheated glass looks liquid, it is not. When most elements are heated, the molecules begin to move freely, which makes them liquid substances that can be dumped. Although superheated glass is similar to liquid material, it remains a solid single molecule at room temperature after cooling. Glass is actually an indefinite solid substance, which is not in a completely fixed structure like ordinary crystals, but is not really liquid. Scientists believe that it may take longer for glass to change its shape at room temperature than for the universe to exist.

To some extent, time will eventually make glass flow, and its molecules will rearrange automatically. But time is so long and vast that glass is always in solid state. For example, scientists have studied an amber that has a history of 20 million years, but found that although it has experienced many different temperatures, it has not become liquid. Although not all glass is as stable as amber, it takes about a billion years for glass to change its shape even if it is in an amorphous solid state.
