1. Cut the lemon and watermelon you need, put it in a cup or beverage bag, and add soda water.
2. Cut the lemons and cut the blueberries briefly. Don't cut them to keep them whole. Put them in a cup or beverage bag, add soda water, or just add ice cubes.
Tips:Soda water has the taste of carbonated drinks, but it is much healthier than carbonated drinks. Lemon detoxifies and is rich in vitamin C. Blueberries have better eye protection effects. It is the best choice to replace carbonated drinks.
