Perfect in it's simplicity and a king among classic childhood firework favorites, the sparkler is hand-held firework that burns at approximately a foot per minute while emitting bright, intense colored flames, sparks, and other effects. Sparklers are generally formed around a thin non-combustible metallic wire that has been dipped in a thick batter of slow-burning pyrotechnic composition and allowed to dry. "Morning Glory" type sparklers consist of a composition filled tube attached to a bamboo rod using brightly colored tissue paper and ribbon. These giant multi-colored torch sparklers change their pigment as they burn down. At 3 feet long they last 3 minutes!
Black snake fireworks are small, non-exploding fireworks that you ignite to push out a growing column of black ash. After the black snake is lit, the firework smokes and creates ash resembling a snake. This happens due to an intumescent reaction. The sodium bicarbonate produces carbon dioxide gas, while the sugar creates carbon containing ash.
