Why does she giggle when I look at her?

I talk to this one girl a lot, and I really like her. We sit next to each other in class and she's always doing something with her hands. So a lot of times I'll sit there and stare into her eye until she notices, and when she does she giggles uncontrollably a couple of times. Why?

Oh, I should add, I'm a fairly normal looking guy, and this has happened more than once.

Oh, an another time, I saw her with a faint smile after I hugged her.
