Kinetics- Explosions of Lycopodium and Other Powders

Explosions of Lycopodium and Other Powders

Description:

A) Lycopodium powder ignites in a closed can, blowing off the lid

B) Lycopodium is lighted in a pile and smolders. Lycopodium is then placed in a turkey baster and blown into a flame. The difference is quite dramatic.
