Party poppers are another well-known and popular noisemaker, especially for children. Inside of the plastic bottle, just above the neck, there's a small explosive charge connected to a string. In the "bottle" portion of the popper are about a dozen tiny rolls of confetti paper. The string is built into the explosive charge in such a way that when pulled tight, the charge explodes, which blasts off the paper end cap and sends out streams of confetti.
Neither pop-its nor party poppers are actually considered to be consumer fireworks. Rather, they are considered "trick noisemakers" which, along with toy caps and cigarette loads, fit into the 1.4S category. Therefore, they can be sold year-round in most toy shops and shopping centers.
