Types Of Fireworks;
FOUNTAINS (Volcanoes)
Fountains are ground effect devices that emit showers of coloured sparks up to 12 meters skywards. They provide wide displays of beautiful colours, and can greatly enhance and complement aerial displays.
Larger fountains consist of multiple tubes fused to go off in sequence, they can easily be confused with repeaters by their shape, but fountains are distinct in that the fuse is on the top, not the side.
How Fireworks Work - Fountains
Single tube fountains consist of a cardboard tube (which may be inside of a cone) that stands vertically on a plastic base. The tube is charged with a composition designed to make lots of sparks, flame, and gas.
At the end of the tube there is a clay plug with a hole drilled into it, forming what is known as a "choke". Without a choke, which allows pressure to build up inside the body of the fireworks forcing the gas and sparks out of the fountain with a much greater velocity.
The fountain composition is often layered as to produce different effects at different stages in the burning. For instance, one layer may burn to produce orange sparks, followed by a layer that produces white sparks and green star fragments.
Repeating fountains are large tubes that contain many single fountains that are fused to ignite sequentially. Because of this, repeating fountains last much longer and usually have a wider variety of effects than single-tube fountains.
Each of the individual fountain tubes has a hole near the bottom with a fuse coming out of it, which leads up to the top of the next tube. This fuse ignites when the tube has almost finished burning, and by the time it does, the next tube has already ignited. This sequence continues for the remainder of the tubes. Sometimes a fuse will lead to several tubes, igniting them all at once to produce an intense spray of noise and colour as a sort of 'finale'.
