A serpentine streamer is a type of party accessory made out of long strips of paper, wound up in a roll, which form snakelike patterns in the air when thrown.
Serpentine streamers can also be used as party decorations, usually hung up from the ceiling across the room, as they form visually appealing serpentines.
Serpentine streamers can be used as party favors.
A less known technique is to blow inside the roll, making the streamer flow out on the current of air.
As party accessories, confetti and silly string can be used.
