Pepsi Challenge

I would like to start by saying that I prefer Coke, but do not object to drinking Pepsi. This weekend, I took an unofficial Pepsi challenge which pinned the current Pepsi against the recently introduced Pepsi Throwback. I never go to the grocery store with the intention of buying Pepsi, but I was intrigued by this particular angle, real sugar. Pepsi Throwback uses real sugar as a sweetener, and not the recently shunned high fructose corn syrup. This is a revolutionary concept for me, since major soft drink brands stopped using real sugar in the early to mid 80's, before I was born. The Throwback can looks retro, and uses the original Pepsi logo and color scheme. The soda was poured into glasses for me, so I would not have any knowledge as to which soda was which. The color was the same and so was the smell (yes, I smelled soda). When I tasted both, it was evident that one soda was significantly sweeter than the other, but which? I chose Pepsi Throwback as the sweeter one and was correct. After the "challenge" I decided to look at the nutritional facts and was surprised, Pepsi Throwback, the sweeter one, actually has a gram less sugar than regular Pepsi.

My next challenge, how many licks does it take to get to the tootsie roll center of a tootsie pop?
