I would like some liquify in a bottle for my own personal use!
Fun video Bob. But wish I could slow it down and see how the liquify tool was actually used, step by step. As it is it's just entertainment, not tutorial. But, I know, not meant to be tutorial. It does show how amazing and powerful PS is and what you can do.
I use the Liquify tool for reshaping quite often, but a saggy ruddy neckline won't get smooth with it as the line will still be noticeable.
Liquify is also fun for things like making flames and swirlies
