I have one tip for opening those darn water bottles or drink bottles that are so hard to get the cap off. Instead of trying to open the bottle by turning it to the right, I first turn the cap to the left like I was trying to close the bottle. Then I turn it to the right and open the bottle. It will open much easier. I do have to say, that this doesn't work every time, but it works more often than not. So, if you don't first succeed, try it again on another bottle.
