I'm throwing a party for a 14 year old girl??? Need ideas!?

How about wet and wild party. Outside .Everybody wears swim suits Buy kiddy pools, water guns and slip and slides. Or even better, on a slight hill put plastic painting tarps(buy at Ace hardware) and one person stands with a hose. Run and slide down it. have water ballon toss. Fun is fun. You don't need to spend a lot of money just invite fun people.
