/diy/ - Do It Yourself

So someone gave me an old CRT TV.

It works.
I opened it, though I tried not to break or desolder anything.
I wanted to use it for some kind of electronic project, but now I feel like breaking it would be a waste. It's a working screen after all.

Could I actually make something out of it that would be worth it?

By the way, I put my fingers under that plastic suction cap, expecting it to shock me, and let's just say it did meet my expectations. But what is it? can I remove it from the tube? It seems to be attached with two wires.
