You're setting yourself up for disaster. First off, lay off on the whole experiment thing. A little joke like that can get weird after it's worn out its welcome. Also, get off the library train. If you want to get to know somebody, do it in a medium generally recognized as one for social interaction. Just ask her if she'd like to get some coffee sometime. It's not a date, so you don't have to get nervous about the whole thing. If you hit it off, just say you had a good time, and depending on how confident you're feeling about the situation, say you'd like to do it again or that you'd like to take her out for dinner. If she wants to see you again, then you can exchange phone numbers so you can make your plans. Assuming that all goes to plan, then you're pretty much set.
