Rather than having to open all the girls you want to talk to, why not just become the center of attention? You could also just use playful opener like this:
You: Hey, i bet you couldn't do a bigger cannon ball than me! Wanna prove me wrong?
Something like that if she says no, tell her, hmmm i was you seemed to be more adventurous!
Anyways, becoming the center of attention by being the funnest guy there is awesome. I remember doing it at this party and i had like about 5-6 girls around me all wanting to be with me. It was pretty cool man, all ranging from like HB6-HB9's. The only bad part was that the HB8.5 that was there and i wanted to be with now thinks im a player because of the event. I still made out with her but she probably doesn't trust me since im a "player" xD
Anyways man, take care, good luck, and have fun at the party!!!
