Best indoors at room temperature.

 

Do NOT leave in a hot car.

 

Extreme heat will expand helium which can cause balloons to pop.

 

DO NOT keep near fans or vents.

 

Extreme cold will shrink helium which can cause balloons to temporarily deflate.

 

Direct sunlight oxidizes latex balloons which causes a cloudy, matte appearance.

 

Balloons pop. Be aware of obstructive objects & surroundings.

 

Static can pop balloons.
