Straight water is too boring for my weird mind, so I mix a ratio of about 85% water with 15% cranberry juice to flavor it up a little. What surprises me is that my mixture will freaking ferment if it sits for more than a few hours! 😜😂😜😂 I left my plastic bottle at work for 4 days over the Christmas holiday and it nearly exploded from the carbonation! 😂😛😂
