It's time for another Good Idea, Bad Idea.
Good Idea: Taking along a can of Dr. Pepper on your drive to your friend's house.
Bad Idea: Forgetting to take the still-mostly-full can of Dr. Pepper inside overnight during single-digit weather.
Needless to say, the Bad Idea happened to me. I've learned that carbonated beverages expand even more than still beverages, creating a lava-like overflow that filled both cup holders in my car. It was definitely Bounty to the rescue, though I was running late and could only stuff a huge wad of paper towels in the cup holder. Luckily, the sun warmed my car just enough to melt all but a small bit of slush that I easily discarded when I got home. I'll try to never do that again.
