What to show high school students on information security?

Question

IT education

A batch of potential applicants will soon arrive at our university, and we, students, need to be given something like a master class (show practical application).
Time is sharply limited, so you need to show something spectacular and not requiring a long time, and designed for the entire audience, and not just for those who are already interested in information security at school.
I hope you have something to offer. Thanks in advance.
