What to do over the Summer with friends?

What to do with my friends this summer ? (im 13, and have like no money ! )?

• its summer, and im already bored. in our group of friends, theres about 7-15 depending on who can do what when. we've already had a week off, and this is what we've done so far: - beach - town - we all went to one girls house and went in her paddling pool and on her trampolines - cinema and thats all we've done, just over and over. we need some 'fresh' ideas but we cant think of any! also, these ideas need to be really cheap ! i.e, not the cinema - its too expensive for us ! all ideas appreciated ! :) thanks x

• Answer:

  find a really grassy hill, and go ice blocking! but to make it really easy and slippery, put dish soap on the hill before... also my friends and i got a plastic tarp like sheets (about 9 feet wide by 500 feet long) at home depot for 9 dollars... got buckets of water and also dish soap and went slip n sliding... you can also do a scavenger hunt which is practically free depending on how you do it... if you have a video camera/recorder on your camera you can do spoofs of your favorite movies or youtube videos...
