Smell Recorder

Say, earlier I was thinking about subjects when I came up with the question "why haven't they invented a smell recorder"? Wouldn't it be nice to be able to play back all of your favorite smells? It would also be fun to pause a smell. I wonder what a smell would smell like in reverse or in slow motion. Not to be gross, but if you take the smell "toot" you would expect it to smell the same way backwards and forwards. Either way you'd probably want to fast forward or fast rewind a toot.

I bet if I was a dog I'd really like to have a smell recorder. Dogs use smells like we use speech. Dogs use fire hydrants the same way people use answering machines. That is, they put their smell on the hydrant so that the other dogs know that they have been near. If I'd have had a smell recorder I would've recorded one of Robert's trips to the hydrant so that Albert could always remember about Robert.
