DrinkSparks.com, via OT.

From “Reactions:” boxes in various locations on the site:

“Natron loves Sparks and often calms his test anxiety by sipping three to four Sparks before, lets say, an astro-physics exam…”

“Hi, these things are great. My neighbor introduced me to Sparks – I give him sandwiches; he buys me a couple Sparks.”

This is great marketing, if somewhat flabbergasting. OT assured me that the beverage is, in fact, used as a study aid by some. America’s future is secure in their hands.

the “Lab” link includes an ingredients list.
