A pyrotechnic device used to discharge colored smoke, typically pink or blue, signifies the sex of an expected child during a celebratory gathering. These canisters are often activated by pulling a pin or twisting a base, releasing a plume of colored smoke that creates a visual announcement. For example, blue smoke traditionally represents a boy, while pink signifies a girl.
These devices play a significant role in contemporary celebrations, offering a dramatic and memorable way to share an important milestone with loved ones. While the tradition of gender reveal parties is relatively recent, the desire to celebrate and share the anticipation of a new family member is longstanding. The use of such devices adds an element of spectacle and excitement to these gatherings.
