We all love our fizzy soda drinks that satisfy our thirst, and they are undoubtedly among the most popular beverages in the world. These delightful soda drinks are a staple at parties, and kids adore them. The history of cold drinks can be traced back to the 17th century. The first lemonade—lemon juice, water, and honey—was the earliest marketed soft drink. In 1676, the Compagnie de Limonadiers in Paris was granted a monopoly to sell lemonade. Europeans attempted to imitate the naturally carbonated waters of springs in the 17th century. Johann Jacob Schweppe developed a process to manually carbonate water in Geneva in 1780.
The development of bottled soft drinks was a marvellous idea, making them a common sight in shops and households. Bottled soft drinks fall under non-alcoholic beverages and contain acids, flavours, colours, water, non-nutritive sweeteners, emulsifiers, preservatives, and other compounds.
The introduction of plastic bottles or commonly knowns as PET bottles (polyethylene terephthalate) made the sweetened soda beverage more convenient for people to carry or store it in their refrigerator. But have you ever imagined why these soft drink bottles are not flat from bottom and why their shape is different from normal packaged drinking water? Don’t worry we have the answer which definitely surprise you.
Well, the answer is cold drink plastic bottles are not flat at the bottom because of the presence of bumps. However, the design of these pet bottles is not just for aesthetics; rather it has a scientific purpose related to the gas inside the soda.
