I made this my Senor year of high school and fermented it in the eves which could be accessed from my front closet on the 3rd floor. I had researched to find it in the library. It turned into "accidental" champaign. Several friends and I enjoyed it before school on the last day of school with strawberries, cherries, crackers and cheese. One friend had a little much...that's another story!!!! Back then the balloon on top was a nickel balloon. I suspect they are more now....you want a good heavy duty balloon. It will be sweet. I don't recommend eating fruit when you drink it!
