Talk:Bending Arts/@comment-3536011-20110409065757

I'm a new user and I have a question. I've read that firebenders are the only benders creating there Element. In the episode entitled the runaway we saw Katara making her own water by her sweat thus making her a waterbender who created there own water.My question is, is an earthbender or an airbender capable to 'create' there own element?
