helium balloon
Ceiling-hugging party decoration
A helium balloon is a balloon filled with helium gas, which is lighter than air and causes the balloon to float.
Children often receive them at fairs and parties; adults use them for decoration.
The voice-altering effect of inhaling helium—making speech high-pitched and squeaky—is a common party trick, though potentially dangerous in excess.
