Yeah, I dunno, just pick something you think is mildly interesting and can be fun with no context. 5 minutes is only 5 slideworth of time, or 3 slides and one 2-minute-long digression.
Introductory material like why we want a difference between voting systems for a single winner vs. for a parliament might be interesting, but just some interesting factoid or digression that takes up 5 minutes is also good.
