Cloud platforms, microservices, and B2B messaging applications are boring to kids, but kids love robots. So showcase something that can move, interact, and be programmed. It can be built out of Lego, or something premade like a drone or Robosapien that's been hacked to be controlled by a Raspberry Pi using Python or whatever. Set it up so that you can "live-code" and take input from kids as to what to make the robot do.
But if you can, do something with a robot. Robots are more inherently, immediately exciting than just about any other computer application, even video games -- even to adults. I spent four years working at well below market rates at a robotics company just to have the opportunity to mess with and program cool hardware.
