Would Your Kids Know What This Is?

So I found this fossil as I was going through some things in my childhood bedroom recently and thought, I wonder if my children even have a clue what it is? So I let each of them examine it and waited for their response...

my 12 year old thought it was a speaker. Smh. My 5 year old said it was a radio. Close, it does say radio cassette player! lol  Needless to say, neither were impressed with it and couldn't understand how this 'weird looking thing' played music. I didn't bother explaining how I used to rewind, fast forward, rewind, fast forward the same song over and over again because there was usually only 1 that I really liked on the whole cassette. That is a lesson for another day! Would your kids know what this thing is if you handed it to them?
