"That's great, Whitney. Can I hand you some more glasses in the same style?"

"Of course. I will check my smartphone in a few minutes. We can do a time machine experiment if you like. I may get a glimpse of the pupils of your school fifty years ago".

"OK, but first keep these glasses on for a moment and we'll see what happens".
