A sparkler is a type of hand-held firework that burns slowly while emitting bright, colored sparks. It burns in high temperature (over 1000°C), so it can be very dangerous.
Sparklers are particularly popular with children. In the United Kingdom, a sparkler is often used by children at bonfire and fireworks displays on Guy Fawkes Night, the fifth of November,[1] and in the United States on Independence Day.[2] They are called phuljhadi in Hindi and are especially popular during the Diwali festival.[3]
