One erev shabbos, lacking oil for light, R’ Chanina ben Dosa took vinegar and said, “The One who commanded oil to burn, He can command vinegar to burn as well.”  The vinegar burned and provided light until the end of shabbos (Taanis 25a).  Due to R’ Chanina ben Dosa’s perfect emuna, a miracle occurred.

I once heard that this gemara may be the source of the famous scene from the Matrix where the boy bent the spoon with his mind, explaining, “Do not try and bend the spoon, that’s impossible. Instead, only try to realize the truth…there is no spoon.”
