~*~my 13th Birthday!! Help?~*~

Hey yall im chelz kay my party is in like 2 weeks and i need some ideas!! my mom is kinda bein retarted and i dunno yet if ima be able to have 6 girls or 4. But anyways. Im gonna have it be a sleep over and i have a couple ideas for it but i need summore. Here are my ideas as of rite now...
~*~get empty soda bottles and then paste pics outta magazines and pictures of all of us at my party on em as like a memoir
~*~write on helium balloons "happy birthday chelz!!" and let em go in the air
~*~write "Chelz`s 13th Birthday" on pillowcases and everyone signs em
And thats all i got so far. Of course were gonna do the classic prank phone calls, dancin, truth or dare, eatin, watchin movies and crap, but i wanna do something realli memorable. I read a post and i was thinkin of hiding a camera and recording my party. If you could gimmie some ideas thad be great!! thanx yall luv ya!!
