I'd highly suggest party tricks, like quarter through soda can, etc.
It really get's people going if your tricks are chosen to the theme of the party. If it's a halloween party, you'd do ghost vision, levitations, etc.
Like AceOfSpades said, try not to use gimmicks. Tweens almost always want to inspect the items. The second you finish, they'll be grabbing at the gimmick. However, Distortion leaves you clean--so that's okay.
Attention grabbers are always good. Using fire in your performance (if you are trained) is something everybody likes. Using colorful spongeballs, d'lites, or such also work.
Things like stigmata, where you alter your body or levitations also do good.
Lastly, involve your audience.
Above all, get a casual routine together and HAVE FUN! Good luck!
