I'd say that all majors are at least potentially cool, and if you go talk to professors in various disciplines, you'll get a chance to meet people who think those disciplines are very, very cool. If the various disciplines weren't cool to the professors, they wouldn't be professing those disciplines.
If you could describe a bit more about things that you like -- what books do you read for fun? are there any classes you especially enjoy? are there any things that fascinate you? -- maybe we'd be better able to pin something down for you.
In any event, unless you have chosen to major in a science, technology, engineering or math field (in which case you'll probably be starting to work on your major requirements as soon as you get to college), I recommend that you take math (because the less you forget from your previous math class, the easier the current one is, so it's worth taking math until you get far enough into the sequence to satisfy your requirements) and English composition (because it will teach you a set of skills that you will use in most of your classes at college, including how to avoid plagiarism; and since plagiarism can come with some stiff penalties, it's worth knowing how to not do it) and 2 or 3 general education classes that look interesting.
Maybe you'll find your cool thing in one of those classes. Maybe not. But the general education classes offer an opportunity to get a taste of many different disciplines, so if you keep taking them, you'll keep learning about various options.
You can also go to the library and browse for interesting-looking books from various disciplines. Actually, that's something you can start now, even though academic libraries are better for this sort of thing than public libraries. And of course you can think about how cool the subjects you study in high school are.
But I fell in love with a discipline I had never expected to during a general education class in my first semester. I had planned on a different discipline entirely, but I was unable to get a class in that area during my first semester, and by the time registration for the second semester rolled around, I had a shiny new major -- and I've never looked back with regret.
The kind of exploration you are beginning to do can be a wonderful experience. You're free in a way you may never quite be again. You're still at the point where all kinds of paths start, and you can choose to go in any of a large number of directions without having to backtrack and lose more time. Good luck with it; I hope you find a major that really works for you and that you enjoy it as much as I enjoyed mine.
