soda

After 12 years the world's biggest beverage company will begin selling 12-packs of the citrus drink on Amazon Monday, and it is the first time Coca-Cola has sold a product exclusively online. The company says the move is a response to a surge of nostalgia for the soda.

Surge, launched in 1996 very aggressively as an answer to Mountain Dew. Initially, reception to the beverage was strong, its appeal faded by the early 2000s.

When the soft drink 7-Up first came out it was 'lithiated'. The soda used to include lithium citrate, which is now better known as a mood-stabilizing drug. Similar to how Coca-Cola famously used to contain cocaine, the makers of 7-Up were capitalizing on the popularity of "medicated" soft drinks at the time.

That's what inspired this experiment. The original 7-Up did not contain a chunk of metal lithium but the end result is entertaining. The solution even ends up working as an indicator, changing from colorful to clear and back again depending on the acidity of the solution.
