One of my "standard"courses has a cultural-contrast theme. Usual end-of-term includes me doing a presentation on whisky (I’m Scottish), students take notes then (optionally) blind-taste or smell a single malt and a blend, guess which is which, then write a compare-and-contrast paragraph on the two.
The smell/taste thing is a bit of a inessential gimmick, but it lightens the mood.
Snag this time is there are quite a lot of Muslim students so it might not be prudent.
Dont have an imam handy. Are Muslims allowed to smell alcohol?
