Welcome to the second edition of the Campus Chaos Challenge, presented by Kodak's new HD pocket video camera. Our first challenge, Surprise Party, yielded tons of results, but there can only be one winner. Congratulations Caldwell, whose video 'Impromptu Bathroom Birthday Surprise' received the highest rating from users. Caldwell will be automatically entered into the Final Challenge and will win either $500, $1,000 or $5,000.

Now for Challenge #2. You have the full weekend to complete the challenge and upload your video by midnight on Monday. If your video is one of the five best, it'll be posted on the homepage the following Wednesday, and users can vote for their favorite. If yours wins, you'll join Caldwell in the Final Challenge. It's that easy. And now, without further ado, the second challenge.

Halloween is right around the corner, but for this challenge there's no need to wait. Put on your most outlandish costume and go trick-or-treating a full week early. Deny any knowledge that your trick-or-treating is premature, and get annoyed when no one has candy to offer you. Catch reaction shots with your camera for maximum effect.

Bonus points for trick-or-treating with a large group, as well as the ridiculousness of your costume.

Simple enough, right? So take your cameras and get out there. Create the best chaos and we'll have $5,000 with your name on it. Not literally.
