What other pop or Kool Aid flavors go well with root beer?!
Answers:
I get why mixing soda with Kool-Aid would be cost-effective, since Kool-Aid is somewhat cheaper than soda, but why would you mix root beer with another soda? If you're going to buy another soda like Sierra Mist, couldn't you just buy more root beer?
Also, why aren't you getting enough water? Can't you just drink more water?
To answer your question, though: I think a cherry kool-aid with root beer might be good!
cream soda or cherry kool aid
Maybe cherry, looks like a lot of the others add this flavor to their. My son adds vanilla to his to.
