Amazing Sweet Citrus Water Punch

Sweet Citrus Water-

~5 quarts of cold water
~2 1/2 cups of sugar
~1 tablespoon lemon extract (the little bottle in the spice section, not the bigger bottle of lemon juice...it will taste drastically different if they are confused!)
~1 tablespoon citric acid (found at Sprouts in the bulk spice section)
~Ice from Sonic (They sell bags of heavenly ice, its really soft balls of ice, yum!)
~Sliced citrus( this adds tons of flavor, and makes it look pretty, you can use oranges, lemons or limes, or all three!)

Stir and Serve!
