Getting her to notice me

Make her laugh. You can gently tease her, but be careful doing this if you do not know her well. You don't want to inadvertently make fun of something very dear to her. Make sure to smile and be approachable, keep a friendly expression and make plenty of eye contact. Eye contact says that you are confident and trustworthy, but also indicates that you are listening. She will be infinitely more drawn to you if she knows you are really listening to what she says and that you value her thoughts. Depending on her comfort level, occasional touches are very good too. A few "accidental" touches to test her out will catch her attention, leave her wondering if it was an accident or not. But then you can make sure she knows you meant to touch her, whether you are just leaning against her a little or playfully poking or tickling.

Poke a little fun at her- but not too much- and make her laugh. that will do the trick :]

Make a lot of eye contact. Smile when you do. Compliment her subtly, not being too obvious that you're into her, unless you want to be. Maybe give her your number and say: "Give me a call sometime." Whatever works for you. And remember it also depends on what type of girl this is. If she's outgoing and feels comfortable around you (you guys talk a lot), then this shouldn't be that hard.... but if you haven't talked that much, you have to be careful not to scare her off. Hope things work out for you. =]

When you talk to her smile, tease her a little, and touch her arm.

Ohh. You can't be too obvious then. Play it cool.
