Have you ever heard of a dust explosion in your area? They are rather common in grain elevators, coal mines, and sawmills. A spark, even due to friction or flame, can set off burnable dust in air to produce a large explosion.This demonstration will illustrate the explosive nature of a powder through the construction of a mini grain elevator explosion. A small paint can will be used to represent a grain elevator. Lycopodium powder will be used as the dust. This explosion will wake up and fascinate even your lethargic students
