Original Purpose: Banishing the dark.
Aha! Use: Smoothing a wrinkled ribbon. Holding the ribbon taut, run it over the surface of a clean, warm (but not too hot) lightbulb. (Caution: To avoid singeing the fabric, don't use a bulb that has been on for more than five minutes or so.)
Reward: No need to fire up the iron or haul out the ironing board for this task.
