Preparing fireworks at Sayn Castle

A firework is an explosive pyrotechnic device that is used mostly for entertainment. The most common use of a firework is as part of a fireworks display.

Fireworks (devices) are made to have these four effects: They make noise, light, smoke, and sometimes produce floating materials (confetti for example). They may be designed to burn with colored flames and sparks. Displays are common throughout the world and are a main point of many different cultural and religious festivals. Independence Day,New Year's Eve and Guy Fawkes Night are examples.
