What are they sparkling?

Sparci are pocket fireworks, most often in the US fourth July. In some countries, they can only be available only a few weeks before the fourth. In other countries and cities, traditional sparklers that most adults are familiar with are no longer for sale or use. Sparky are very nice, but unfortunately they are the main cause of injury related to burns associated with personal fireworks. One side of the rod is to be held, while the other side is immersed in some metal fuels that can release color, usually only one color. Common metals that burn well include iron and aluminum, to which chemicals can be added as potassium nitrate, potassium chlorate, carbon or sulfur. To obtain certain colors, adding barrya, copper and strontium produces green, blue/green and red sparks.

Metals burn at very hot temperatures, up to 3000 F (1649 ° C), which is responsible for their high incidence of injury. Especially because sparklers are often given to young children, they are something like a disaster waiting. Young children and even older should be carefully monitored to hold sparklers apart. Shirts with long sleeves and shoes with a nearby flow can also help prevent sparks from landing on the skin. A bucket of water and access to water source is an important safety feature in the use of sparklers or other personal fireworks.
