How do I change a light bulb I can't grip?
Take a piece of duct tape and wrap it in the shape of an "O", with the sticky side of the tape on the outside.  Stick the loop of tape to the face of the light bulb such that it is secure. Put your hand (four fingers) inside the loop and twist counterclockwise to loosen the bulb.
