Mental Floss:

Even though I’m fairly ancient, I’ve never seen a Model T outside of a classic auto show. So I realize that there are many things that have been obsolete since the elastic waistband was invented and would confound anyone under age 70. But what about some common items that have come and gone within the last 30 or so years? See how many of these you recognize, and how many of them would puzzle your kids or grandkids.

Interestingly, while I have heard about all of them, five of them I’ve never actually seen in real life (#2, 4, 6, 8, 10). How about you? And which ones would your kids not be able to recognize?
