Gaze into there eyes.

Any flirt knows that making eye contact is an emotionally loaded act. Now psychologists have shown just how powerful it can be. When pairs of strangers were asked to gaze into each other's eyes, it was perhaps not surprising that their feelings of closeness and attraction rocketed compared with, say, gazing at each other's hands. More surprising was that a couple in one such experiment ended up getting married. Neuroscientists have shed some light on what's going on: meeting another person's gaze lights up brain regions associated with rewards. The bottom line is that eye contact can work wonders, but make sure you get your technique right: if your gaze isn't reciprocated, you risk coming across as a stalker.
