Party popper

It emits a loud popping noise by means of a small, friction-actuated explosive charge that is activated by pulling a string.

The charge or compressed air blows out some confetti or streamers and emits a popping sound.

There are also party popper revolvers on the market, which use a Speedloader — style cartridge filled with six-party popper charges inserted into a normally colourful plastic device loosely resembling a pistol or revolver.

Party poppers have been known to cause serious eye trauma and other facial injuries when aimed at people.

[4] Party poppers are classified as "indoor fireworks," and as such, they are subject to legal restrictions in some places.
