Hmmm... I just thought of something. Lithium is an alkali metal, all of which react with water in a way that results in a metal hydroxide (mixed with the water) and hydrogen gas (that escapes to the air). Lithium is the weakest of these metals and thus its reaction with water is very mild.

Given that fact, we could try to convince buyers of this product that they can easily make their own Golden C water by dropping a piece of stronger alkali metal, such as Cesium, into pure water...
