…can be taken in a carbonated soft-drink without significantly altering its taste.  What is more amazing than this, is that in so doing, one does not alter the “fizziness” of the beverage in the least.

One must be careful not to mix it in too quickly, because it will foam somewhat; however not nearly as much as when other dissolvable substances are added to such beverages.

I had expected the foaming to take place, but I did not expect enough carbonation to remain afterwards.  Somehow the resultant mixture was little changed–even after all the agitation necessary to dissolve 17 grams of the the stuff.
