Gymnasts and Dancers

Are you a gymnast who likes having calluses on your hands? I've heard that you can make the calluses bigger by soaking them in brine solution. Really?

A problem with bigger calluses is that they tend to hurt. Dancers also want calluses, though on their feet--not their hands. Dancers keep their calluses 'under control' by soaking them in tea. The acid in the tea softens the calluses some.
