Empty Bottle Potion

The Empty Bottle Potion is a Magic Item that is seen as little more than a joke. Drinking the liquid of the potion provides one with an empty bottle suitable for the storage of a potion. When the liquid is drunk, the original bottle it is in will shatter and a new bottle, almost identical to the first, will appear in the drinker's other hand. The new bottle is made of otherwise completely mundane glass.
Despite the lack of any real usefulness, the potion is still popular for its distinct sarsaparilla-cola flavoring and bubbly consistency. Mages often have their apprentices practice potion brewing with creating Empty Bottle Potions due to the relatively simple ingredients and low chance of disastrous mishaps.
== History ==
The Empty Bottle Potion was originally made as a mundane carbonated beverage by a merchant of the name of Johann Anderson, sold in glass bottles similar to ones used by mages and marketed with the slogan, "A taste like magic." The bottle also included instructions for use similar to those found in tomes of potion recipes, saying that "imbibing the enchanted fluid contained within this bottle will provide you with an empty bottle." Somewhere along the line, an actual mage came across the Empty Bottle Potion and created the actually magical version as a joke and it's popularity has caught on ever since. 
Eventually, the mundane variant would go onto become the soft drink, EB Potion.
== Variants ==
There is a nameless cursed variant of the Empty Bottle Potion that still has the original bottle shatter when it is imbibed, but does not provide a new bottle. This variant often tastes slightly off and more flat, though still 'carbonated'.
