Yes, you can! We encourage you to have fun with the bubly bounce™ drops and mix to find a great blend for you. If you’re trying to combine different flavors, be sure to add up to ¾ tsp TOTAL of your bubly bounce flavor mixes to the carbonated water (28 fl oz / 840 mL) in a 1L SodaStream bottle. Please remember to always fizz water before adding any flavor. Enjoy your tasty bubbles!
