Though it is hard to tell what type of 'fluff' you're talking about, food wise, hair wise, fabric wise? Next time be more specific and you can get better answers. :) Sorry if mine wasn't what you were hoping for.
fluff? i dont get what you mean, but i know how to make fluffy paint, just miz shaving cream, paint, and white glue, and there you go, fluffy paint :)
Cotton, Yarn, Fur, Marshmallows, Butter. If you mean HAIR wise...
Hairspray, gel, combs, hairbrushes, and certain shampoos.
