How to install experimental package?

Question

I would like to install an experimental Debian package.

I'm currently having problems with the older version so I figured it's best to upgrade and try that one because I can always switch back. Anyway I want to install this package:

Experimental: http://packages.debian.org/experimental/deluge
Normal: http://packages.debian.org/wheezy/deluge

I have wheezy debian.

Add

deb http://ftp.debian.org/debian experimental main contrib non-free

to your /etc/apt/sources.list or into /etc/apt/sources.list.d/experimental.list then execute

apt-get update
apt-get -t experimental install deluge

See Debian Wiki and apt-get manual

 -t, --target-release, --default-release This option controls the default input to the policy engine; it creates a default pin at priority 990 using the specified release string. This overrides the general settings in /etc/apt/preferences. Specifically pinned packages are not affected by the value of this option. In short, this option lets you have simple control over which distribution packages will be retrieved from. Some common examples might be -t '2.1*', -t unstable or -t sid. Configuration Item: APT::Default-Release; see also the apt_preferences(5) manual page.
