I handed the floppy disk to a third-grader and asked him what he thought it was.

“A … bottle opener?” he wondered.

I’m a firm believer that kids should learn about what the world was like when their parents and grandparents were growing up. Record players and in-car ashtrays can be lessons in how a previous generation was raised, reminding us of what was important, creating connections and sparking conversations.
