Now that we can use the internet to access almost anything you’d want to see and/or hear, we should make museums that archive different smells. You could find new smells you might have not experienced otherwise, or find some nostalgic smell to bring you back to a moment in your past.
There is, or once was, such an exhibit at the Exploratorium in San Francisco in the 1980s. They have you smell things via tubes and you try to guess what it is. Science museum. It’s since moved to the piers. So I’ve heard. It used to be cheap to go there; now, I’ve read it’s very expensive.
