ShyGuy took my idea.
Anyways, you tie the Kevlar to two paper clips, and then use the rubber band to launch one of the paper clips across the chasm until it sticks to something strong enough to support your weight. Then you throw the Chicken across, to save for later, and attach the paper clip with kevlar over on your end to something that can support your weight. Of course, these are industrial super-strength paper clips, those giant ones, since you didn't specify. Now you hang from the kevlar and go across. The chicken will be useful to make jokes and keep yourself entertained.
