This is what I show kids at the youth centre I work. A more innocent version obviously, like changing the text below the Google logo. They can figure out the potential nefarious uses themselves :p This is for the ones that did't really came to learn but thought they could fire up a gaming website or facebook. Something to keep their attention instead of just saying "no, not allowed". I really like that CSS transition/rotation trick, made a note of it, because it seems like a perfect step up after you've gotten the concept of being able to change text. If anyone knows more of these simple "party tricks", please do post them here :-) Another one I like, surprisingly popular among the younger kids (7-9 or thereabouts), are the two linux command line tools "sl" and "cowsay". Two characters to display an ASCII steam locomotive in that weird black hackers rectangle? Yeah! Those two are actually super-educational, because they're not installed by default on most systems so you quickly explain/show them you need to "sudo apt install" them first (tell them "apt is kind of like the app-store and sudo means you want to do it as the super-user", not entirely correct but good enough for now). The more clever kids actually remember this and next time they want to show another kid, they partially remember they needed to do something with that apt install line (and then ask me what it was again, exactly).
