The Zipper Candle Trick for Frozen Jackets

In Chicago, during the biting cold snap of January 2014, a kid named Jamie stood shivering outside his apartment because the zipper on his parka locked up halfway. Jamie's mother ran back inside, grabbed a plain white candle from the kitchen drawer, and did something that changed the way people in their building handled winter jackets. She rubbed the candle wax directly along the teeth of the stuck zipper, pushing the wax deep into the metal grooves. What made this work, even when hot water and brute force had failed Jamie fifteen minutes earlier? Candle wax is solid at room temperature but melts just slightly from your hands' warmth, creating a thin, nearly invisible layer that allows the metal zipper to glide over itself like it's new. Even after several trips in and out through snow and slush, Jamie’s zipper refused to jam again, proving the trick with a single stubby candle can sometimes outsmart a $100 jacket.
