Melon Juice

1. Cut cantaloupe in half crosswise and with a spoon, scrape off seeds and inner pulp.
2.  In a bowl, place seeds and pulp with one cup of the water, and mash with the back of a spoon to extract flavor. Using a colander, strain juice and discard seeds. 
3. Hold the cantaloupe half firmly and shred flesh using a fruit shredder or the tines of a fork into thin strands.
4. In a pitcher, combine shredded melon, extracted juice from seeds, simple syrup, and the remaining 3 cups of water. Stir well and chill in the refrigerator until ready to serve

For the Simple Syrup

1. In a saucepan over medium heat, combine sugar and 1 cup of water and bring to a boil, stirring occasionally, until sugar is dissolved. 
2. Remove from heat and allow to cool completely.
