Scratch-N-Sniff

There are a lot of great smells out there (plenty of bad ones too). I use a lot of scratch-n-sniff stickers for my students and I was thinking of things that would make a good smell for the stickers. Here are some thoughts:Wet pavement

Smoke from a chimney.

BBQ

I love the smell of Noxzema!!

Here are some Scratch-n-Sniff that already exist:

Apple

Peppermint

Caramel

Rootbeer

Stinky Stickers: Onion, Pickle, Licorice, Dirt!!

My favorite: Coffee!! It might smell like the coffee candles in which case I won't be super impressed. I'm intrigued. I might have to order these.

What do you think would make a good Scratch-n-Sniff smell?
