Using this Magic Potion is a breeze! First, open the 2.29 oz. bottle. Then, take the tablet that comes with it and drop it inside the bottle. Just sit back and wait for 5 minutes. During this time, the magic happens, and a new color will show up. Remember, you'll get a random flavor and color with each order, so it's always a surprise! As for maintenance, keep the bottle in a cool, dry place. And when you're done enjoying it, make sure to recycle the bottle if possible. Have fun discovering the different flavors and colors!
