At 18 December 2008 , Qatar celebration of Independent Day. Many events before that time, until the peak was 18 december night at 10.00 pm . yeahh...fireworks ..wonderful & amazing view ! Almost 1 hour we watch them.now I just write about How does fireworks work & fireworks invented.
Fireworks invented :
About 2000 years ago , in China , a military cook accidentally mixed together charcoal, sulphur, and a mineral called saltpeter, which promptly exploded when it was exposed to heat.
Within a few centuries, Chinese monk had learned how to use this formula for peaceful purpose, stuffing it into tubes to propel colourful fireworks into the sky ( usually as a way of celeberating birthdays or fending off evil spirit).
How does a sparkler work ?
they seem harmless enough, but sparklers-hand-held fireworks that burn slowly, emitting colourful spark-can reach temperature as high as 2000 degrees fahrenheit ! Sparklers are made from metal rods that have been dipped in flammable material, then allowed to dry. The reason they emit sparks when they 're lit is that the solid fuel contains flecks of aluminum or iron, which emit characteristic colours as tkey ignate.
