Product Details

Have you ever heard of or read about a dust explosion in your area? They are rather common in grain elevators, coal mines and sawmills. A spark, even due to friction, 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. The explosion will “wake up” and fascinate even your most lethargic students. Teacher Demonstration Notes included.

Concepts: Surface area, combustion.
Time Required: 15 minutes
Materials Provided: Lycopodium powder, candle, nail, paint can with lid, Beral-type pipets.
