I have a cast iron pan with excessive warping/bulging so I got on Google and searched "straighten warped cast iron pan." First thing that popped up was Google's top post which was an article posted by Leaf.tv.

I followed their instructions and videoed the procedure. This is what happened! I really wanted to see if the technique worked or not. Not only for my own knowledge but to educate others that have warped cookware. There are no YouTube videos on straightening cast iron so I wanted to share my experience whether it was good or bad just so others knew the outcome.
