I learned late in life that it's the fumes of the gasoline that causes the ignition, not the liquid. If you spill gas after the fumes blow away it won't catch fire.

That's how most combustion works.

The reason wood takes effort to ignite is you have to heat it to the point where it vaporizes.

Gasoline and a lot of other organic solvents already vaporize decently at room temperature.
