We have invented devices to record what we can see, and devices to record what we can hear.
Why haven’t we invented something to record what we can smell?
How would this work if we did?
\[When I am travelling I really wish I could record the way things smell, because smell is so strongly evocative of memories and sensations.\]

Sight and sound are forks of energy. Light waves hit our eyes which allows us to see and sound waves hit our ears and let us hear. We can record the light waves and vibrations and store those patterns.
Recreating that is fairly easy, allowing us to replicate sights and sounds.
Smell on the other hand is molecules hitting our nose. We have no way to replicate molecules, so you need to store every type to recreate smells, which would be near impossible.
