I have been thinking about scratch-and-sniff stuff lately. I used to love that stuff. Stickers and books that had little pictures that you would scratch and then you could smell them and they would smell like the picture.
One of my friends pointed out that they always seemed to have a skunk one on whatever it was. Who wants to smell that.
Wikipedia says that the sense of smell is easily stored in long-term memory and that it has a strong connection to emotional-memory. So I wonder why they don't use scratch-and-sniff in text books. I would become a genius overnight. If someone wrote a novel and added scratch-and-sniff pictures I bet it would be an instant classic.
Manufacturers should put a scratch-and-sniff on the outside of their products. Imagine if you were shopping at the grocery store and you wondered if you might like a certain flavor of ice cream. You could scratch-and-sniff it and get a pretty good idea of what it might taste like.
Probably don't need scratch-and-sniff diapers, meat or that kind of thing. But then nobody is forcing you to actually scratch the thing.
I look forward to the day when scratch-and-sniff technology will be rediscovered. I just hope the technology isn't being suppressed by the olfactory challenged.
