Have a bonfire! You could roast hot dogs and make smores! If you all just end up sitting by the fire, you can gossip and play truth or dare. If you don't want to do that, you could play bloody mary, get water balloons and have a water balloon fight!

You can rent a projector and watch a movie outside,just have them bring blankets and pillows .I did it once worked out great.

Candles.

I'm turning 14 in a week and I need a party idea. I'm having about 15 friends over, all girls, and I want to do something outside. It's not a sleepover, but it's going to be from 7-10(ish) so it is going to be dark. I want this to be fun, so what are some things I could do, including snacks because we will serve dinner. Thanks!
