So many types of fireworks, so little time! A popular category of pyrotechnics are “fountains,” sometimes also called “gerbs” among professionals. These fireworks are lit on the ground and push the exploding compounds up and through the cone-shaped construction to create a beautiful eruption of streaming sparks. The science behind fountains is interesting. These fireworks are made by stuffing a specially-designed, conical tube with pyrotechnic chemicals. When the user lights the fuse, the compounds start to burn and emit gases. The buildup of gasses need to escape and are pushed, along with the fiery contents of the cone, through the narrowed “choke” at the top of the tube.
Fountains come in many colors, sizes and special effects. Smaller fountains are usually packed with up to 200 grams of pyrotechnic compounds and last around 30 seconds to one minute while large fountains are typically 500 grams, the maximum amount allowed by law at the consumer level, and can stream for up to three minutes. For obvious reasons, 500 gram fountains are very popular with firework enthusiasts. For a bigger bang, multiple 500 gram fountains can be fused together for a longer-lasting effect. Popular 500 gram fountains include Bug Zapper, Rhythm & Blues, and Snake Chaser; each has a different assortment of changing colors, crackling, whistles and other interesting elements.
Keep safety in mind when lighting 500 gram fountains. Follow the local laws and regulations concerning the use of these fireworks items in your particular area. Also, for both your personal safety and that of the audience, always follow the manufacturer’s directions for lighting 500 gram fountains. These big fountains can spew sparks in a large fallout area and could also cause bodily harm if they malfunction and are not being properly handled.
