Boy/Girl Swimming Party

I need some help. I am going to have a summer party with my 7th grade classmates and I need some ideas! I am gonna have some music playing by the pool too. But any game ideas that aren`t LAME! This is my second year of doing this (it`s and annual thing now) and I want this year to be even better than last year`s! Thanks!
