what are those things you blow into at parties
Party horn A party horn (or party blower) is a horn formed from a paper tube, often one that is flattened and rolled into a coil, and which unrolls when blown into, producing a horn-like noise. The item is not known consistently by any term in English, also being known by a number of local variations, neologisms, and individual terms, often containing variants and synonyms of blowing (puffing, blow-out etc.) and noise (whistle, squeak etc.)[citation needed]
