RANDOM FACTS ABOUT SPARKLING WATER 💡
Carbonated Water was associated with having many medicinal properties. The first spa (yeah, the spa you are thinking about), was built around a natural spring that had naturally carbonated water! 
Now that we think about it, how good would a fizzy drink taste after a massage?
The story of how Krusty the Clown from ‘The Simpsons’ came into being revolves around Seltzer or Sparkling Water.
Krusty the Clown, born Herschel Shmoikel Pinchas Yerucham Krustofsky, was born in the Lower East Side of Springfield and is the son of Rabbi Hyman Krustofsky. Hyman strongly opposed Krusty's wish to become a clown and make people laugh, believing that it would distract him from his religion, wanting the boy to go to yeshiva instead. However, Krusty performed slapstick comedy behind his father's back. One day, he was performing at a rabbis' convention when one joking rabbi squirted seltzer on him, washing off his clown makeup. When Rabbi Krustofsky found out, he disowned his son, and did not speak to him for 25 years.
Krusty was later reconciled with his father with the assistance of Bart and Lisa Simpson. 
It has been scientifically proven that Sparkling or Carbonated Water tastes different from normal water and the interesting part is, it’s not the fizz. Sparkling Water’s carbonation is experienced through our sour taste receptors. An enzyme called carbonic anhydrase 4 reacts with the CO2 and transforms it into bicarbonate which leaves behind a free-floating acidic proton triggering our sour taste bud receptors and giving the sensation of “feeling” (instead of tasting) zesty carbonation. 
When sparkling water is cold, the carbon dioxide molecules have less energy to escape. Therefore cold sparkling water is fizzier and also stays fizzier for longer.
