Expose it. Develop it in something like Dektol. Bleach it with a potassium dichromate bleach, which dissolves silver but has no effect on halides of silver. Expose it to light--just turn on the darkroom lights (make sure the paper box is closed first!!!) Redevelop it in Dektol, then stop and fix before washing and drying.
