If you want to really blow their minds, make them use a dial phone.
I do have an old dial-phone, and when daughter was young - well, it did indeed blow her mind, particularly how slow it was compared to push-button dialing.
She also one day asked me what sort of movies we rented and watched when I was a kid LOLOLOL!
She couldn’t believe it when I said we had only one TV channel, and a black and white TV - and movie rentals were unheard of!
