Homemade Sparkling Apple Juice

From: http://www.onegoodthingbyjillee.com/2011/10/homemade-sparkling-apple-juice.html

• 2 cans apple juice concentrate (thawed) (We splurged and bought the Wal-mart Great Value brand!)
• 1 (2 liter) bottle club soda (Again, we decided to pull out all the stops and bought the exclusive Kroger Store Brand)
• Mix.
