Do you know which the popular soft drink 7up is called "seven up"?
well, according to wikipedia
A myth exists that the 7 Up name comes from the drink having a pH over 7. That would make it neutral or basic on the scale; however, this is not the case, as the 7 Up pH is close to 3.79, similar to other drinks of the type.[4] The real origin of the name is unclear,[5] though Britvic claims that the name comes from the seven main ingredients in the drink,[6] while others have claimed that the number was a coded reference to the lithium contained in the original recipe, which has an atomic mass around 7.[7] Britvic also claims that the name be a result of the fact that 7 Up was bottled in 7-ounce bottles (Coca-Cola and most other soft drinks were bottled in 6-ounce bottles). Other research has been made and it is known that 7up got the name from the candy bar seven up. A man Pearson sold the name to a company and then discontinued the candy. [6]
