An on ground demonstration of how plastic spheres are activated for use in wild fire control.  \nThe round spheres contain potassium permanganate.  Before dropping from the helicopter, they move through a tube and injected with a green water and glycol solution, making the spheres combustable.  The exact combination of chemicals in each sphere determines how long it will take to ignite and how intensely the fire will burn.  From helicopters, they are dropped onto the ground to initiate a controlled burnout to remove debris from the ground - becoming a fire control line in that area.
