Fizzies are effervescent tablets that dissolve in water to create a fizzy, flavored drink. They were first introduced in the 1960s and became popular as a fun alternative to traditional soft drinks. Fizzies come in various flavors, such as grape, orange, and cherry, and are often marketed as a low-calorie beverage option. To use Fizzies, simply drop a tablet into a glass of water and watch it fizz as it dissolves. The result is a bubbly drink that can be enjoyed by people of all ages. Fizzies are often associated with nostalgic memories for those who grew up in the 1960s and 1970s.
