This is why containers made from PET plastic keep carbonated beverages colder , more flavorful, and fizzier.

不过这气泡确实和塑料中的成分有关系.

The reason for this is because of a cabin's lower air pressure making it even easier to release the CO2 in the drink, making even fizzier than usual.

其原因，是机舱的气压比地面低，这使得饮料里的二氧化碳更容易释放，让它们比平常更容易起泡。
