How to Illuminate a stiff link chain on the trail

Does the chain on your bike skip? One common reason for this to happen is stiff link chains. This video features a professional mountain bike mechanic demonstrating how to illuminate, or make loose, stiff link chains if you get caught with them out on the trail. If you don't do this, and your chain skips enough, it's going to come off and you are going to stack, so make sure your bike is maintained properly!
