Frosty fruit punch slush

To crush ice with minimal mess, put cubes in a zip-top storage bag, push the air out, and seal the bag. Place the bag on the counter and hit it with a rolling pin or a meat mallet until ice is in small pieces. Put ice into a blender. Sprinkle drink mix over ice and add the water. Cover and blend until smooth and icy; stirring 2-3 times during blending. Serve immediately with a spoon and a straw.
