Temps dropped into the subzero kill-you-if-it-could range beginning on Sunday night and continuing through early Monday morning, though they moderated to the balmy teens above zero F. during the day today. The temps didn’t get to me, this being an age of central heating and Gore-Tex, but it did lay waste to some cans of soda in the garage.

This isn’t the first time we’d forgotten some cans in the garage, only to have them become a chemistry demonstration: solids tend to take up more space than liquids.

We probably forgot them because “Diet Mist Twst” brand isn’t all that memorable. (Where’s the missing i?) We acquired the cans as part of a 12-can package, though I don’t remember why we bought that particular brand. Probably because they were temporarily cheap and represented something different. Worth a try. As a drink, it’s OK. Basic unmemorable lemon-lime.

A year ago, E.J. Shultz wrote in Ad Age that “Sierra Mist is about to the leave the mountains behind. The PepsiCo-owned brand is removing the word Sierra from its name as it becomes “Mist Twst” as part of a major branding overhaul that will put more emphasis on taste…. The change is the latest makeover for the lemon-lime-flavored soda brand, which has undergone multiple overhauls since launching in 2000.”

Ah, it used to be Sierra Mist. I didn’t notice the change. Or any of the “multiple overhauls.” As brands go, it’s no Coca-Cola. Or even Pepsi. But what is?
