Flat Sparkling Water Paradox 

The Flat Sparkling Water Paradox is a VERY well known hypothesis that the only true way to describe sparkling water is by describing it as flat water.

Which some people would just say is still water but they would in fact be incorrect. This is because despite the flat taste of sparkling water, it is still carbonated, therefore, meaning it is still sparkling water.

So as a result of this carbonated beverage tasting flat we come to the understanding that this is indeed the Flat Sparkling Water Paradox.

Friend 1: This sparkling water tastes awful, it just tastes like flat water.

Friend 2: That makes no sense but also hundreds of sense at the same time.

Friend 1: Wow that sounds like some real Flat Sparkling Water Paradox
