A toothpick catches fire a lot more simply as it heats up in a short time.
A fire piston that made warmth and fire with the compression of air in a small tube of bamboo was a complex machine invented and Utilized in southeastern Asia, Indonesia, along with the Philippines. About 1800 a steel fire piston was independently invented in Europe.
