Crystal Pepsi (1990s)

Crystal Pepsi, a clear cola variant introduced by PepsiCo in the early 1990s, became a cultural phenomenon despite its brief market presence. Its transparent appearance defied expectations of what a cola should look like, sparking curiosity and intrigue among consumers. The marketing campaigns, featuring artists like Van Halen, were memorable and contributed to the product's initial popularity. While it didn't last long on shelves, Crystal Pepsi remains a symbol of 90s innovation and experimentation in the beverage industry, fondly remembered for its novelty and bold marketing efforts.
