Helium is sensitive to temperature changes. Cold air causes the helium to shrink, which makes the balloon appear to deflate, although it still floats. Heat can cause the helium to expand and the balloon to burst. Latex balloons are also sensitive to light, and balloons of any kind are weakened by dirt and dust. shannon messenger mallowmelt cookies recipe
