I didn't even realize how often I used balloons in the classroom... And I don't think this is a complete list! Share your ideas in the comments!

I use balloons for a project with constellations. My first graders use the balloon as a mold to create a dome. They paper mache the balloon, then when dry, we paint them black for the night sky, then use skewers to punch holes for the constellation patterns. An electric tea light candle is put inside of the dome to illuminate the constellations.
