Editing Firecracker (section)

===Ingredients ===

Firecrackers are generally made of cardboard or plastic, with [[flash powder]] (a mixture of oxidizer and metallic fuel), [[cordite]], [[smokeless powder]], or [[black powder]] as the propellant. This is not always the case, however. Anything from match heads to kerosene and lighter fluid has been used successfully in making firecrackers.{{citation needed|date=October 2020}} The key to loud firecrackers, however, although in part lying in the propellant substance, is pressure. The entire firecracker must be very tightly packed in order for it to work best. Flash powder, however, does not need to be packed tightly, and should not be.
