- Pour the Gatorade into a shallow, freezer-safe container. 
- Add a pinch of salt to the mixture and stir gently to combine evenly. 
- Place the container in the freezer. Every 30 minutes, take it out and stir vigorously with a spoon to break up ice crystals. Repeat this process 2-3 times until the mixture becomes thick and slushy. 
- Once the Gatorade has a icy, granular texture, pour the soda over the slushie base. 
- Gently fold the soda into the slushie with a spoon, mixing just until combined and bubbly. 
- Return the container to the freezer for another 10-15 minutes until fully frozen and scoopable. 
- Remove the container from the freezer and use a spoon to scoop the icy, vibrant slushie into glasses. 
- Enjoy immediately as a cool, chunky, and flavorful summer treat!
