A fun thing, I did this at my 14th b-day and it was a hit, is split everyone into 2 teams and go around the neighborhood playing a game I call Bigger or Better. What you do is give each team a toothpick and set them out into the neighborhood going door to door asking for something Bigger or Better than the toothpick, say they give you a box then you go to the next house asking for something bigger or better and they give you a bag of candy, at a designated time meet back at your house or wherever you started and have a judge decide who got the biggest or better thing. This game is actually really fun and this way you're not crammed in yur house or anything and you'll be surprized with what kinds of things people end up giving you!
