Dust Flame

This demostrates how increasing the surface area of an object and its oxygen to substance ratio will increase a substance's burn rate. A pile of pine tree pollen, which is not normally flammable, is placed into a funnel below a candle. It is then blown up toward the candle's flame, dispersing throughout the air. Its surface area increases as does its oxygen to substance ratio. When the flame somes into contact with the pollen, it burns almost instantly in a great rush of light and heat, which would never happen would a pile of pine tree pollen come into contact with a candle flame.
