If you have a problem opening jars or bottles, try some of the following methods:

- Try using latex dishwashing gloves or rubber computer mouse pad as they give a non-slip grip to the jar lid or bottle cap, or 

- Tie some rubber bands around the lid or cap, then cover a cloth over it and turn, or

- Turn the jar or bottle horizontally, carefully run some warm water over the lid or cap. The heat of the water will expand the lid or cap.
