Subject: iterating over array of variables - can't change them?

title="Title"
subtitle="Subtitle"
body="Body"
[title,subtitle,body].each {|item| item.downcase!}

This successfully sets the original variables to "title", "subtitle",
"body"

BUT

[title,subtitle,body].each {|item| item=""}

has no effect.

Why doesn't this work? How can I make it work?

thanks
