Website collecting user data

Hey.
I don’t know too much about hacking, but I want to do something. Let me explain.

At school, I’ll be doing a presentation about online privacy. At the end of the presentation, I want to do something special. Here is what I’m planning to do:

I want to create a website that people can join when they are in my WLan hotspot. This website doesn’t need to have anything special on it, it can just be a blank page.
But when they go on that website, I want to be able to see their data, which I would collect using JavaScrip. https://www.deviceinfo.me/ Is a good example on what I want be able to see, altough it doesn’t need to be everything that’s there. Only the most important stuff.

I think this would show, how much data really is exposed. Of course I would first ask for their permission to collect their data. Do you think it’s a good idea?

Now I already said this, but I don’t really know much about hacking/programming.
If anyone knows how I would do this, or it was already done, please let me know. Also, if you have other good ideas on how I could show this interactivly, please let me know too.

Thanks for reading. Peace.
