fire is very dangerous element, but in same time its very important for life in our beautiful planet, so in this short article, i am going share with you 5 fact's you probably didn't know about fire
camp fire
1- Earth is the only known planet where fire can burn. Everywhere else: Not enough oxygen.
2- Oxygen supply influences the color of the flame. A low-oxygen fire contains lots of uncombusted fuel particles and- will give off a yellow glow. A high-oxygen fire burns blue.
3- Fire makes water? It’s true. Place a cold spoon over a candle and you will observe the water vapor condense on the metal
4- The ancient Greeks started fire with concentrated sunlight. A parabolic mirror that focuses solar rays is still used to ignite the Olympic torch.
5- Every 52 years, when their calendar completed a cycle, the Aztecs would extinguish every flame in the empire. The high priest would start a new fire on the ripped-open chest of a sacrificial victim. Fires fed from this flame would be distributed throughout the land.
bonus fact- Spontaneous combustion is real. Some fuel sources can generate their own heat — by rotting, for instance. Pistachios have so much natural oil and are so prone to heat-generating fat decomposition that the International Maritime Dangerous Goods Code regards them as dangerous
