In the video, a person is seen holding a matchstick and lighting it on fire. The person then proceeds to use the lit matchstick to ignite a pile of wood. The flames from the matchstick spread to the wood, and the person continues to add more matches to the pile, causing the fire to grow larger. The person's actions are deliberate and careful, ensuring that the fire spreads evenly throughout the wood. The video captures the process of starting a fire, from the initial ignition to the growth of the flames.
