A party horn (also known as a party blower or noisemaker) is a horn formed from a paper tube, often flattened and rolled into a coil, which unrolls when blown into, producing a horn-like noise.
It is not consistently known by any single term in English, but by a number of local variations, neologisms and individual terms often containing variants and synonyms of blowing (puffing, blow-out etc.)
[citation needed] Modern variations have a plastic mouthpiece to prevent swift degradation from the moisture of the mouth.
The paper tube often contains a coiled metal or plastic strip that rapidly retracts the horn after it is blown.
Others have a brightly colored feather attached to the end which vibrates in the outgoing airflow.
