Can you start a fire without a spark?

Answer 1

Yes you can. It's called spontaneous combustion and it's a result of matter reaching its auto-ignition temperature.

Technically 4 things are needed for a fire to happen: fuel, oxidizing agent (such as oxygen), heat, and chemical reaction.

A good example of this is oily rags stored in a closed container. Even though the oxygen level in the container may be low, it enough to support combustion. The rags begin to build up heat due to the chemical reaction. Once enough heat builds up to the rags lower flammable limit, the rags and oil auto ignite. This results in an explosion blowing the lid off and allowing more oxygen to get to the fire and continue burning.

Answer 2

You need heat, oxygen and fuel.

Enough heat in proximity with fuel and oxygen will cause spontaneous combustion. A spark is an intense, localized heat source, but isn't necessary. You can focus heat with a magnifying glass and combinations of certain chemicals/catalysts. You can also increase the oxygen level which reduces the amount of heat required for combustion.

Answer 3

You cant start a fire, you cant start a fire without a spark
This guns for hire even if were just dancing in the dark

Answer 4

take a soda can, and some fine dirt, scrub the concave (bottom) part of the can till its really shiny, then u can reflect sunlight off it to make a fire.....old survival trick..
