Do you remember when you could scratch a picture in a book and smell the picture that you were scratching? Strawberries? Yum! Mint? Fresh! Dog Poop? Yuck!
In this episode of Dirt Nap City, we'll explore the fascinating history of products designed to stimulate our sense of smell, from the quirky to the cutting-edge.

First, we'll delve into the world of scratch-and-sniff stickers and books. These innovative products, popularized in the 1970s and 80s, allowed readers to experience a multi-sensory reading experience. We'll discuss the science behind these fragrant wonders and share some of the most iconic and bizarre scents that were once available.

Next, we'll turn our attention to the ambitious experiment in cinematic history known as "Smell-O-Vision." This short-lived technology aimed to enhance the movie-going experience by releasing synchronized scents into the theater. We'll examine the technical challenges, the public's reaction, and the lasting impact of this pioneering attempt to engage all the senses.
