Demonstrate Flammability of Untreated Surface

What happens here

The video begins by showing a close-up of a propane torch applying a direct flame to an untreated, light-colored surface, which appears to be a section of particle board or similar wood-based material. The surface quickly chars and burns where the flame makes contact, demonstrating its low fire resistance and how easily it can become a fire hazard.

Goal: A propane torch is applied to a standard, untreated surface (likely a piece of wood or cardboard) to visually demonstrate its rapid flammability and charring under direct flame.
