Since Luft is red, and the balloon we saw was white, it’s 99 weiß Balloons.🙂
Luft is ‘air’..................
Luft is a word for air. Rot is the German word for red pronounced roht. Red balloons in the song is a way to add a syllable to make it flow. It also sounds better than air balloons since balloons contain air and it would sound stupid.
