What are some cool party ideas?

What are some really cool ideas for a party with fourteen year old girls. I have a pool and a big room, so any cool ideas like games or stuff like that?

oh well im15 so I can help
if theres boys 7 minuets in heaven is always fun
theres like cops and robbers I love that game
theres movies ahead of time
but my favorit game is see who can eat more marshmelloes, you get every girl to shove one in at a time (the big ones) with out spitting them out, then see who can swallow them all, it sounds boaring but it is so fun. Me and my friends did it for a party and they were popping out of our mouths. it makes every one crake up.
good luck
P.S. I highley suggest the marshsmellos

You should have an Existentialist themed party. You provide the espresso and cigarettes and the guests provide the ennui. It's a formula for an absolutely fabulous party...I mean, not that you'd care.

No but seriously, I'd go for a Golf Pros and Tennis Hoes sort of affair.

I think doing make-overs, pedicures, nails getting done is a great pass time with movies playing and snacks like popcorn, cupcakes. I think these are all sweet things but I am out of touch with today's teens since I was a teenager about 18 years ago. LOL
I hope I helped anyway.
