These were from the future. How could they possible had the technology to create such a thing? I mean, you would get a piece of paper, scratch it, and it smelled like the picture?! Is that even possible?

Yes it was; through the magic of micro-encapulation!— whatever that is.

The only time you knew you did well on a paper or test was when you got one of these stickers. The paper got passed back, you see that big fat A on it, and you knew there was going to be a banana or strawberry sticker smell wafting into your nose.

What was your favorite smell? Where are they now?
