In chapter 8 of HP and the Chamber of Secrets, Nearly Headless Nick 
receives a letter from the Headless Hunt. This letter is said to be 
transparent.
 Can´t ghosts in the HP series touch human (wizard to be exact) 
equipment/material? When NHN makes Peeves crash the cabinet over 
filch´s office to save harry, is this beacuse he himself cannot do 
it? 
 So in that case, do they have their own, transparent ghost-stuff? 
Everything from ink to chairs? (if so, how do they make those things?)
