If you or a family member has arthritis, opening standard child-safety pill bottles can be a real pain. Use a bit of Sugru to give the lid a textured grip that makes it easier to open.
This idea comes from Instructables user Surfer24. All you need for this hack is to open a packet of Sugru and mould it into a long "snake" shape. Wrap the Sugru around the the bottle lid tightly and let it cure for 24 hours before use.
If you don't already have Sugru on hand you can order it from the official website.
