Medieval Memes
If we’re grateful for one thing that’s lasted the test of time, it’s Play-Doh. It’s a wonderful thing for kids to express their creativity with – or, in the past, a way to express other people’s creativity with! Instead of passing notes in class, you could use this to send a message to a friend.

Simply place it over your message or comics strip, and the Doh will copy the markings! Of course, you just had to ensure the teacher didn’t read the message. That was easy enough – roll the ball up when they came looking and pretend you were just playing. And people say kids are smarter nowadays! I would like to see a Gen Z person come up with this.
