How to roll r's?
Well, for some strange reason, no one can show me how to roll my r's. However, although I know that this might sound a little strange, I thought that, maybe, if someone wrote how to do it, I could do it by following their directions. Unfortunately, whenever I ask someone to do that for me, they just say "What? I am not doing that. No way, José" or "You crazy, girl?"
Please, please, don't say that, because I always get so annoyed, and you do not want a frustrated, annoyed and furious Selena Murin PM-ing you. Trust me, my frustrated, annoyed and furious PM's are R-rated. (Even though I am under 17)

This is a tongue twister for practicing to roll your R's,
Erre con erre cigarro,
Erre con erre barril,
Rapido corren los carros, Cargados de azucar al ferrocarril.
When my eldest son was a little boy, he was not able to pronounce the 'rr' sound and changed it for a 'gg'. I took him to a therapist who placed him in front of a mirror. The tip of the tongue must be just behind the ridge situated between the upper gum and the palate but should not touch it. Then you must try to exhale while you vibrate the tip of the tongue. In four sessions he was able to do it. The movement is the same as in the English 'r' only harder.
Hope this helps. 
And this one from a recent forum discussion:
I had the same 'problem'. Keep at it. It'll happen when you least expect it! 
HI Selena, have a look at this, this might help you.
Try saying "pot of tea" as fast as you can repeatedly
