Combine the Red Ropes and ½ cup of water in a skillet and bring to a simmer over medium-low heat. Continue cooking and stirring occasionally, adding a splash more water if the candy starts sticking to the pan. Once the Red Ropes have melted, remove the pan from heat and scoop the candy into a bowl to cool.
Add another ½ cup of water to the skillet along with a tablespoon of sugar. Bring to a gentle simmer and stir to dissolve the sugar in the water. Use a spatula to scrape up any candy bits stuck to the bottom of the pan. Pour the sugar water into the bowl with the melted candy.
Fill a blender with 3 cups of ice cubes and pulse to crush. Transfer the crushed ice to a bowl and place it in the freezer until the candy has cooled.
When the melted candy/sugar water has cooled to room temperature, add it to the blender. Blend on high speed to break up any remaining solid chunks of candy. Add half of the crushed ice and blend again. Divide the remaining crushed ice between two glasses and pour the Red Ropes mixture over top. Enjoy immediately.
