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?
\[When I am travelling I really wish I could record the way things smell, because smell is so strongly evocative of memories and sensations.\]
In: Technology
Scents work by way of chemicals entering your nostrils and interacting with your brain stuff in there.
So while it is easy to reproduce light and sound, an object that “replayed” smells would have to contain all of those chemicals, which would be extremely expensive, impractical, and potentially dangerous.
