Subject: duplicating characters in a string

If i have a string "abc" and want to make it like this "aabbcc", how do
i go about it?

I thought convert it into an array and then use string.map{|x| x << x}

though i havnt tested that yet. Is there a better way or a string method
that saves me from having to convert it into an array?
