Dear 100 Hour Board,
This one's a long shot. I've heard that our sense of smell possibly has the strongest link to memory of all our senses. I'm a believer - one nostalgic smell to me is the smell of the Indiana Jones ride at Disneyland. It's a unique, musty, sweet smell that I like and that transports me back in time instantly. My question is twofold: first, what could create that Indiana Jones smell? Second, I walked by the ground floor of the LSB parking garage today and smelled almost the exact same smell! What makes that particular smell, and are the odors related? I guess that's three questions.
First of all, know that you're not alone in enjoying the smell.
However, other frequent Disneyland users are less generous in their descriptions, with my favorite comparing it to "18 kinds of butt."
Disney doesn't give out details about their particular aromatic endeavors, but this reddit thread suggests the most likely source is propylene glycol, from the fog effects, and hydraulic oil.
I am unfortunately far from BYU campus and the LSB, but if I had to guess I would venture there's some kind of science going on in there that involves the same chemicals.
