In the festive seasons and on the special occasions of our life we love to crack fireworks. Some people love to go for the one that produces sound and some love to see the light and different images that produce in the sky during night. First of all the chemical reaction of the objects and raw materials is very important. This is the base of any firework. This is called pyrotechnics. This ensures that the raw material go for an exothermic chemical reaction and thus produces light, smoke, heat and sound. Some crackers come with excessive sound as well! Find your machine on internetÂ

Sunglasses allow better vision in bright daylight, and may protect one's eyes against damage from high levels of ultraviolet light. Typical sunglasses are darkened for protection against bright light or glare; some specialized glasses are clear in dark or indoor conditions, but turn into sunglasses when in bright light. Most sunglasses do not have corrective power in the lenses; however, special prescription sunglasses can be ordered. Specialized glasses may be used for viewing specific visual information (such as stereoscopy) or 3D glasses for viewing three-dimensional movies. Sometimes glasses with no corrective power in the lenses are worn simply for aesthetic or fashion purposes. Even with glasses used for vision correction, a wide range of designs are available for fashion purposes, using plastic, wire, and other materials.
