Add the sugar water to a blender.

Notes
Storage :
To Store: Keep any leftovers in the freezer. Allow the Slurpee to thaw just enough to pour into the blender to pulse to return to a Slurpee consistency.
Tips:
You can substitute concentrated Kool-Aid liquid drink mix for the powdered Kool-Aid. Do not add the sugar if you choose to use the Kool-Aid liquid.
You can store the Slurpees in the freezer for up to 20 minutes before serving.
You can use a sugar-free substitute for the granulated sugar.
