My personal favourite to illustrate infinity (as possible) and some math concepts around it is still the video "How To Count Past Infinity" from Vsauce: [VIDEO] "This is math, not science." (~12:30)

Completely offtopic, except for math and title, but highly recommended while waiting for the movie: "How To Count Past Infinity" [VIDEO]

The issue is that there are different infinities. The infinity the parent is talking about, the one that you generally run into in calculus class and the like, is straightforward. The research in the past century was about what happens _past_ infinity, e.g. ordinal numbers. I'm no mathematician either, so I'll stop there before I embarrass myself. The most accessible resource I found was this VSauce video [1]. [1] [VIDEO]

There is one English definition of infinity, but when applied to ordinals ("degrees of freedoms"), you get different mathematical concepts of infinity. Vsauce's explanation is approachable: [VIDEO]

VSauce is a science channel which I find both entertaining and educational. Fun and fast paced and often mind-bending. [VIDEO]
